Trick To Be More Productive

work

What’s up ? This is THE stephane ANDRE !!! I watched an Olivier Roland’s video  and I learned some good stuff.

Have you ever finished a day completely exhausted and after analysis, have the impression of having accomplished nothing ?

Don’t worry, it has happened to me and it happens to everyone a few times. The truth is that it’s important to understand that there is a difference between being productive and being busy. It’s really something that you have to remember often.

To be busy

Here is an example, imagine that you spend all day pushing a building with hands. It’s serious, you really want to move the building. It’s obvious that at the end of the day, you’ll be very tired but the building will not move.

You’ll have to spend a lot of energy, give a lot of effort but the results are negative, the building did not move a millimeter. In fact the efforts you make aren’t systematically correlated to the results you will get.

With the building’s example, it’s easy to understand that this task destined for failure but with the activities of every day, it’s more complicated to identify.

Let’s use another example. Imagine that you spend all day pushing a block of stone on the sand. At the end of the day, the block of stone will have been moved a little bit (and this is a better result than with the building). But is there a way to move this block of stone faster ? Yes, with a crane, it’s more efficient and it takes less effort. It’s true that finding a crane requires a lot of energy and time, but the crane allows you to have better results more impressive. With the crane, you can move the block of stone in 30 minutes to the destination.

To be productive

be productive

Often the methods to be productive requires a lot of effort and you have the impression to build nothing, but when the methods are put in place, it will give you continuous results without asking you a lot of effort.

Today, after my training, I spoke with a gym employee about blogs. He wondered why I had a blog because for him blog are dead. It’s true that blogs are less fashionable than videos and it’s true that a blog takes years to have an interesting traffic to build a company.

But what he doesn’t see and what the majority of people don’t see is that if the content of the blog has no expiration date, 5-20 years later, your blog’s content will have always value and will be usable. If yo create content based on news, 2 months after your content is no longer valuable and no longer usable.

And it must be added that the blog’s mailing list is more efficient than social media’s subscribers when it comes to promoting your product/service. It also makes me think that since 2005, every year, people say email is dead, ahhaha haahahah.

Vision

It’s not easy to realize that we’re busy instead of being productive and it depends on our perception. By having a clear vision of what you want, you create a company that is at the service of your life rather than your life at the service of your company. Creating content with no expiration date to educate people is my vision. On internet, one of the keys to success is to be able to create the maximum content without expiration date to not be dependent on fashion phenomens.

With this vision, it helps you identify when you’re busy and when you’re productive. This skill allows you to search for what is most effective to reach your vision. At first, there are things that you consider effective and they’re not and vice versa. The process to reach your vision is to explore new things to move forward and grow.

Have you already identified things in your work that you think are effective and in fact they aren’t (like pushing a building with your hands) ?

Have The Chance That You Deserve

chance

What’s up ? This is THE stephane ANDRE !!! I watched an Olivier Roland’s video  and I learned some good stuff.

We’re lucky that we deserve. It’s true that there a bit of luck in everyone’s success. If I take my case, I recognize that I was lucky to be born in an industrialized country with internet and a good education. But I also created some of the luck that allows me to have my lifestyle today.

We aren’t all born under the same star or not with the same cards, that we can’t change. The thing we can do is to do with what we have to get something better. Having this state of mind is essential to having a better lifestyle. It’s important to be proactive. Whatever the bad luck or the handicap, you have the possibility to realize your dreams. It will be harder than other people but it’s possible with perseverance and patience.

Made with what you have

use what you got to have what you want

Here’s what you have to say to yourself : « My dream is that, maybe I’m not very lucky to succeed and maybe people will think I’m crazy, but I’m going to try to do something. I’m not going to do like the majority of people, I’m going to act, I’m going to do different and do interesting things ».

The truth is that the greatest craziness is to believe that by always doing the same thing, we will have different results. By always doing the same thing, we always have the same results. If you think you deserve better than that in your life, change your comfort, change your actions.

Seneca says something interesting in « Moral Letter to Lucilius ». He talks about people who commit suicide. He says it’s a paradox. It’s a paradox to give up life. What Seneca means is that it’s more constructive to try to change the actions that led to the results of being disgusted with life rather than leaving life.

It’s true that there are also elements that are outside our control or elements like psychology, depression, but whatever your despair, you can choose to change your actions to have another result. I will not lie to you, it will not be easy and it will not happen overnight. The main thing is that you have to try new things, experiment new things, get out of your comfort zone. It’s like this quote : « It’s when we walk that we risk failing ».

Go to another world

comfort zone

The majority of people are in a frozen environment. They’ve been doing the same things for years, they’ve been thinking the same way for years and their lifestyle is stagnating. Get out of this environment to experiment other things and meet people who think differently but share the same values as you. It’s these types of people that will motivate you to do things you never thought you’d do.

When you dream of something, it always seems impossible to you. Publish a book, start a company, change job because it’s frustrating, all that, you feel like it’s outside of your world. It’s true that it’s outside of your world but you have the possibility of making it a reality. Look, imagine that you are on the beach and you have to go to the mountain but you don’t know the way. The majority of people will stay on the beach because it’s more comfortable and safer.

It’s true that it’s safer to stay on the beach but over time, it becomes boring. The best plan is to go towards the mountain and on the way, you will find the first step. At this point, you can ask how to go to the second stage. At the second stage, you can ask how to go to the third stage, etc. In this way, gradually, you reach the mountain learning a lot of new things.

To start a company, it’s the same plan. You find an idea. Then you write a 2-3 pages project that explains how this idea can become a company. Then you look for how to finance this company. Then you create a product or service and you contact prospects, etc. It’s obvious that when you start these projects, you don’t really know the stages. Do this plan now with the knowledge you have, this will allow you to demystify the process and find the first stage.

We must stop dwelling. You have goals, you have frustrations, you want to do things to improve your lifestyle, run the plan. Go to the first stage and get information for the next stage. There is never a perfect time to start (that’s an excuse to procrastinate). You have to start imperfectly and do it anyway. It’s the only way to get the chance you deserve.

Chi-Square Test With More Than 2 Categories

tableau chi square test

I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

In this article, we will do a Chi-square test with more than 2 categories. We will use the A/B test « Country » which has 3 categories which corresponds to 3 countries : German, Spain and France. Select « Gender Actual » tab, make a copy with a right-click and select « Duplicate ».

tableau chi square test

Name the tab « Gender Actual (2) » by « Country Actual ».

tableau chi square test

In « Dimensions », move the variable « Geography » over « Gender » in « Columns » to replace « Gender » with « Geography ».

tableau chi square test

tableau chi square test

Here’s how to do an A/B statistical test when there are 3 categories. We’ll start with the classic method and then I’ll show you another way to do Chi-square test with any number of categories.

Let’s start with the classical method. In this case, there are 3 categories so we can’t use the online tool of the previous article. In the previous article we used an online tool with only 2 categories « Sample1 » and « Sample2 ». That’s why we’re going to use another online tool, click here  .

tableau chi square test

In this online tool, we can enter the values without using the total values. That is, we enter only the number of observations in each category. We simply need to enter the values that are on our A/B test. And I’m going to show you how to turn our A/B test into a table. In this way, it will be easier to enter the values in the online tool without making any mistakes.

Go to the « Show me » tool at the top right.

tableau chi square test

Click on « text tables »

tableau chi square test

tableau chi square test

Click on « Swap Rows ans Columns » button.

tableau chi square test

tableau chi square test

Cool, now you have a table arranged in exactly the same way as the online tool.

In the online tool, we will select 2 rows and 3 columns.

tableau chi square test

As we have 3 categories and 2 possible results, we enter our values exactly as in the table we just created on Tableau.

tableau chi square test

Perfect, our table is ready. You can click on the « Calculate » button.

tableau chi square test

tableau chi square test

As you can see, we observe the same thing as the other online tool. There is our indicator « p » value which is less than 5%. Which means there is a meaning.

tableau chi square test

This statistical significance means that these results are valid for the total number of the bank’s clients and not just for the sample of 10 000 clients. We observe similar differences with A/B test « Country » whose results are based solely on the sample of 10 000 clients. We can conclude that in the total number of the bank’s clients, it’s the clients in Germany who are more likely to leave the bank. This is how we do things cleanly.

You saw, this online tool limited by 5 by 5 tables so you can’t use this tool when you have 6 categories or more. But fortunately it’s possible to do Chi-square test with any number of categories. It’s a special method and for you to understand that, I’ll give you a theoretical explanation.

Here we have 3 countries : German, Spain and France.

tableau chi square test

What we’re trying to compare is the clients number leaving the bank in each of these countries.

tableau chi square test

With our basic A/B test based on a sample of 10 000 clients, we obtained 16% for France, 32% for Germany and 17% for Spain. Now the question is : « Do we observe the same results on the total clients number of the bank ? », it means : « In general, does the country have a significant effect on the clients number leaving bank ? ». Germany has the largest number of clients leaving the bank so the idea is : « Why would we need to compare the 3 countries at the same time ? ».

tableau chi square test

If we do an A/B test statistical test with Germany and France and we get a significant difference in the clients number leaving the bank between these 2 countries, then that would mean that in general, the country has a significant effect on the clients number who bank. Indeed, if we find by comparing Germany and France that the Germans are more likely to leave the bank than the French, we can consider that Spain will not change anything. Germans will always be more likely to leave the bank than the French. Maybe there will be a different relationship between Germany and Spain but there will always be a statistically significant difference between France and Germany with a larger number of clients leaving the bank in Germany than France.

Here is a way to confirm that this logic is true. There is a test and the participants of this test are German, Spanish and French. Imagine that this test was done without looking at what is happening in Spain. Now you get the result and you ask yourself the question : « Would the results changed if you added Spain ? ». The answer is « no » because there is no interdependence between Germany, Spain and France. That is, the decision to leave the bank in France and Germany doesn’t depend on Spain. And therefore, it’s quite correct to separate the categories by putting 1 aside to compare the 2 others. And as now we have 2 categories, we can do a Chi-square test with the online tool that we used in the previous article.

So let’s go back to our worksheet and put a country aside to compare only 2 countries. Select « Country » tab.

tableau chi square test

What we observe is that the difference between Spain and France is very small, so it wouldn’t be interesting to do a Chi-square test between Spain and France. It’s more interesting to do a Chi-square test between Germany and France and to prove that there is a statistically significant difference between these 2 countries. This will be enough to conclude that the country has a statistically significant impact on the clients number who leave the bank.

Selects « Country Actual » tab.

tableau chi square test

We will use the online tool of the previous article, click here  .

We will make a copy of « Country Actual » to have a bar chart with absolute values. Select « Country Actual », right-click and select « Duplicate ».

In « Show Me », select « horizontal bars ».

We also need total absolute values, which means the total number of men and women. There is a very fast way to get that. Right-click on the vertical axis and select « Add Reference Line ».

tableau chi square test

Then in « Value », click on the drop-down on the right and select « Sum » to have the total sum of the observations.

tableau chi square test

And in « Scope », you select « Per Cell » option to specify that you want the total sums for each category, male and female.

tableau chi square test

Now, we have the total sum at the top of the bars. We will modify labels to have the absolute values. In « Label », we will change « Computation » to « Value » and click on the « OK » button.

tableau chi square test

tableau chi square test

tableau chi square test

Here’s how to enter the data :

For « Sample1 » in #success, you enter 810 because there are 810 people who left the bank. For « Sample1 » in #trials, you enter 5014 because there are 5014 people in total.

For « Sample2 » in #success, you enter 814 because there are 814 people who left the bank. For « Sample2 » in #trials, you enter 2509 because there are 2509 people in total.

tableau chi square test

Here is the verdict : « Sample2 is more successful ». « Sample2 » corresponds to German’s clients and #success is :« yes, the client left the bank ». This verdict means that of all the clients from German are more likely to leave the bank than clients from France. And look, there is something important, it’s « p<0.001 ». This means that the « p » is strictly less than 0.001. As you can see, « p » value is very small, which concludes that the tests are statistically significant.

Ooh, there’s another thing I wanted to show you with the tab « age » with the 2 bar charts in parallel.

tableau chi square test

As you can see, there are many categories (more than 5) because each category corresponds to a 5-year ago group with clients of the bank aged from 15 to 90 years old. This is a lot of comparison but it would be a good exercise for you to find what are the 2 categories to compare that shows that there is a significant statistic difference.

I give you a hint, compare slices from 50 to 54 years old or from 35 to 39 years olds. In fact, you should compare all peer categories where you observe difference on this basic A/B test. Do a basic A/B test with absolutes values. Then do a Chi-square test to check if the difference is statistically significant, I mean, if the result is valid for the total number of bank’s clients.

This is a way to statistically validate the insights we see onTableau. You see, it’s not very difficult and it’s effective. Here is a way to find insights on Tableau and validate them.

Feed Your Brain Is Important

feed brain

What’s up ? This is THE stephane ANDRE. I watched an Olivier Roland’s video  and I learned some good stuff.

To be successful in the areas that interest you, there is an important principle that is to nourish your brain in a healthy way. It’s the same principle for your body. If you eat fast food burgers every day, you’ll become fat, your self- esteem will decrease, your energy will decrease, your libido will decrease and your lifetime will decrease.

If you feed your brain every day with the « burgers » of information, I mean news (newspaper and tv), you’ll have a negative state of mind. The information of these newspapers or these media are 95% negative and 80% of this information, you’ll forget them in 15 days. These are events where you have no impact on it, it uses your brain’s energy for noting and because of this negative information, you become more and more worried.

Good food for the brain

The most efficient and accessible way is to read books of excellent quality. When you read books of excellent quality, you have access to the best brains in the world for an affordable price, or even free if you go to a library. With books, you also have access to the best dead brains. It’s not because the person is dead that this person has to stop giving us value.

Purpose of reading these books is to allow you to have a solid foundation for achieving your goals. To start, you need to create a list of books and use the SMART goal method (SMART => specific, measurable, accessible, realistic and defined over time). If you want more detail, go to a search engine like Google of DuckDuckGo and enter : SMART goal.

For example, you can give yourself the goal of reading a book a month. I advise you to write a summary page for all the books you read. Scientific studies have shown that when you write the summary, you will remember more things and you will memorize more things than if you only read the book. Here are 2 scientific studies here  and there .

.

Check the book’s quality

books

To start, reading reviews on books that interest you on Amazon is a good place to start. It’s clear that it’s not done by experts but you can see people who like and hate the book. It’s up to you to do your own analysis of the numbers of positive and negative comments. If there are a lot of comments (at least a hundred), it’s a good sign.

It’s possible to access lists of books complied by people who read a lot of books. It’s obvious that these lists will never correspond at 100% to your objectives but it allows you to find pearls. If you want to train in business and personal development, Josh Kaufman’s Personal MBA  is excellent. It’s not necessary to like all the books of Personal MBA but most are extraordinary.

Action

Here is a simple exercise that I propose to you. Find 5-10 books of excellent quality that can help you achieve important goals for you. Determine a deadline (1 year) and calculate how many books you should read per month and how much time you have to spend every day reading.

I’m curious to know the books you found. Share this in the comments section and let’s go .

Boost Your Charisma

charisma barack obama

What’s up ? This is THE stephane ANDRE ! I watched an Olivier Roland’s video  and I learned some good stuff.

To increase my charisma, I discovered a completely counterintuitive trick. This trick is a state of mind. This is a trick that Seth Godin shares in his book « Tribes » . In this book Seth Godin explains the importance of internet. Internet isn’t just about doing business with customers/prospects, but it’s a real tool for building a tribe or community.

The principles for building a tribe or community with internet are to share quality content and to clearly explain your values to bring together people who share the same values as you. Seth Godin says something very interesting about charisma, he says that most people think that yow have to have charisma to get the idea when it’s the opposite. The simple fact of having the idea gives charisma. It’s deep right ?

In everyday life

 

everyday

 

I’m sure you’ve seen this situation :

  • There is a person who loses consciousness on the sidewalk Quickly a person must take responsibility for the idea of caring for the person who has lost consciousness

  • There is a car accident. Quickly a person must take responsibility for the idea of dealing with traffic to secure the area.

In situation where there is no designated leader, a person must take the initiative, without permission, to take responsibility for the idea of managing the situation.

As you can see, it does give charisma to this person and the others will naturally accept him/her as a leader and listen his/her orders, until the situation returns to normal.

The question, I’m asking you is : « In the project that is important to you, could you take responsibility for the idea of taking care of your tribe or community that shares the same values as you and to do evolve the project ? ». Tell me your answer in the comments section.

Validate Data Mining In Tableau With A Chi-Square Test

validate validation

I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

In this article we will start using statistics. Don’t worry we’ll do something simple, we’ll use the Chi-square test in a basic way. There is a special section to learn how to do statistics at an advanced level.

I’ll explain why we’re going to learn how to use the Chi-square test. The results we have with theses 2 bar charts are good. We see on theses 2 bar charts that age has a significant impact on the rate of client leaving the bank. We also see in which age groups the clients leaves the bank the most and which age groups the clients leave the bank the least. With that we have good insights.

In the A/B test « Gender », we can see that there is a correlation between the male and female sex and the choice to leave the bank. But as I said before, this A/B test is basic. The results of a basic A/B test visually shows us what is probably happenning in reality but we aren’t 100% sure of these results. To validate these results, we need do to use statistical tests like Chi-square test.

Doing a report based on basic A/B test is very risky and you can have completely false insights. I don’t advise you to do it (unless you want to leave your job). It’s for this reason that using Chi-square will help us to have strong insights.

Chi-square will allow us to know if our results are statistically significant. Our results are based on a sample of 10 000 clients and Chi-square test will tell us if these results are due to chance effects or if these results can represent all the client of the bank.

For example in our A/B test « Gender », we observed that in our sample of 10 000 clients, women are more likely to leave the bank compared to men.

tableau data mining science chi square test a/b test

Now, we aren’t sure if the results of this sample represent the behavior of all the bank’s clients.

To use basic Chi-square test, we use an online tool. Click here  .

tableau data mining science chi square test a/b test

On internet, there are plenty of websites to do a Chi-square test but we’ll use this one so that you can understand how it works. To do a Chi-square test, we need to use absolute values and in our A/B test we have percentage.

Let’s go back to Tableau. We’ll create a new tab with a version of A/B test with absolute values. In this way, we keep the A/B test with the percentages. Do a right-click on the « Gender » tab and select « Duplicate ».

tableau data mining science chi square test a/b test

Name the new tab « Gender Actual » to specify that it’s absolute values.

tableau data mining science chi square test a/b test

To have the absolute values, move « Number of Records » in « Measures » to the « Marks » area and put it over top of « SUM(Number of Records ».

tableau data mining science chi square test a/b test

tableau data mining science chi square test a/b test

Move « Number of Records » in « Measures » to « Rows » over « SUM(Number of Records ».

tableau data mining science chi square test a/b test

Cool, we have our absolute values.

tableau data mining science chi square test a/b test

We also need total absolute values, which means the total number of men and women. There is a very fast way to get that. Right-click on the vertical axis and select « Add Reference Line ».

tableau data mining science chi square test a/b test

Then in « Value », click on the drop-down on the right and select « Sum » to have the total sum of the observations.

tableau data mining science chi square test a/b test

And in « Scope », you select « Per Cell » option to specify that you want the total sums for each category, male and female.

tableau data mining science chi square test a/b test

Now, we have the total sum at the top of the bars. We will modify labels to have the absolute values. In « Label », we will change « Computation » to « Value » and click on the « OK » button.

tableau data mining science chi square test a/b test

tableau data mining science chi square test a/b test

Perfect, we have the total amount of observation at the top of each bar : 4543 women and 5457 men. We have what we need to use our online tool.

tableau data mining science chi square test a/b test

OK, I’ll explain how this tool works. « Sample1 » and « Sample2 » correspond to the independent variable « Gender ». You choose in which order you enter the data, « Sample1 » for men or the opposite. In our case, we use « Sample1 » for women and « Sample2 » for men.

« #success » corresponds to the result Y=1, which means in our case « yes, the client left the bank ».

« #trials » is the total number of observations, which means the total number of women in « Sample1 » and the total number of men « Sample2 ».

That’s how you enter the data :

  • For « Sample1 » in #success, you enter 1139 because there are 1139 women who left the bank. For « Sample1 » in #trials, you enter 4543 because there are 4543 women in total.

 

  • For « Sample2 » in #success, you enter 898 because there are 898 men who left the bank. For « Sample2 » in #trials, you enter 5457 because there are 5457 men in total.

tableau data mining science chi square test a/b test

Here is the verdict : « Sample1 is more successful ». « Sample1 » corresponds to women and #success is :« yes, the client left the bank ». This verdict means that of all the bank’s client, women are more likely to leave the bank than men. And look, there is something important, it’s « p<0.001 ». This means that the « p » is strictly less than 0.001.

tableau data mining science chi square test a/b test

« p » is the value that indicates whether an independent variable has a statistically significant effect on a dependent variable. In our case, the independent variable is « Gender » and the dependent variable is « Exited », which is : « yes, the client left the bank ». So « p » is strictly less than 0.001, which means that the independent variable « Gender » has a statistically significant effect on the dependent variable « Exited ». This shows us that out of the total number of bank’s clients, women are more likely to leave the bank than men.

This is how we use Chi-square test with this online tool. This is the same principle on all online tools that you can find on Google or DuckDuckGo . You can repeat these instructions that I gave you with other tools, you will get the same results.

It’s cool with the Chi-square we validated the A/B test and to specify that this A/B test is validated, we’ll color the tab in green.

Right-click on the tab, select « Color » and select « Green ».

tableau data mining science chi square test a/b test

tableau data mining science chi square test a/b test

Perfect, now we’ll validate another A/B test. Selects « HasCreditCard » tab.

tableau data mining science chi square test a/b test

We’re going to create an A/B test « HasCreditCard » only with absolute values. To save time, right-click on « Gender Actual » tab and select « Duplicate ».

tableau data mining science chi square test a/b test

We’ll remove the green color on the tab « Gender Actual (2) ». Right-click on the tab and select « Color » and « None ».

tableau data mining science chi square test a/b test

You rename the tab « HasCreditCard Actual ».

tableau data mining science chi square test a/b test

Move the variable « HasCrCard » over « Gender » in « Columns ».

tableau data mining science chi square test a/b test

tableau data mining science chi square test a/b test

Excellent, everything is ready to do a Chi-square test. We’ll remove « Exited » labels to better see the absolutes values. Make a click and drag out.

tableau data mining science chi square test a/b test

tableau data mining science chi square test a/b test

Perfect, let’s go back to our online tool. In this case, « Sample1 » is « no », which means client who don’t have credit card and « Sample2 » for « yes », which means clients who have a credit card.

That’s how you enter the data :

  • For « Sample1 » in #success, you enter 613 because there are 613 clients who left the bank. For « Sample1 » in #trials, you enter 2945 because there are 2945 clients who don’t have a credit card.
  • For « Sample2 » in #success, you enter 1424 because there are 1424 clients who left the bank. For « Sample2 » in #trials, you enter 7055 because there are 7055 clients who have a credit card.

Let’s look at the verdict, it’s « No significant difference ». « p » value is very high, it’s above 5%. This confirms that the independent variable « HasCrCard » has no statistically significant effect on the dependent variable « Exited ». That was the conclusion we had made when we had done the A/B test with percentages.

We had seen that there was 21% of « Exited » (clients who left the bank) in the category « no » and 20% in the category « yes ». With these results we concluded that most likely the variable « HasCrCard » had no impact on the rate of clients who left the bank. Chi-square test confirms our conclusion and we can put the tab « HasCrCard » in green to say that it’s OK.

Right-click on the tab « HasCreditCard » => « Color » => « Green ».

Excellent, now, you can do a statistical A/B test with 2 categories. Soon, we will do statistical A/B tests with more than 2 categories.

Challenge Your Intelligence

I watched an Olivier Roland’s video  and I learned good stuff :

Have you ever heard that : « If you’re smart and you’re always surrounded by idiots, you’ll always be right ».

Sincerely, there is a deep truth in it. This corresponds to this quote « If you’re the smartest person in the room, you’re in the wrong room ». We are human beings and it’s easy to follow your ego. It’s easy to stay in an environment where we’re always right because subconsciously we want to be around people who adulate us or put us on a pedestal.

When we look around, we see people who are successful and who stay in a bubble where they’re surrounded themselves with people who will always agree with them. It’s in our human nature not to like the contradiction of what we are and the values we defend. All of this is logical, we have success, we developed values and a life approach that we tested in the field and we don’t know others ways.

It doesn’t mean that in any case it works and that doesn’t mean that there are not other ways to succeed.

A group of intelligent people

 

mastermind group

When was the last time you were in a room where you felt that you weren’t the smartest person in the room and that you learned new things ?

What is interesting when yo participate in a mastermind group is that you’re surrounded by brilliant people who don’t hesitate to say when there are obvious things in you and you don’t see them. It allows you to change your point of view and forces you to face your own limiting beliefs.

Often during a mastermind group, there is a « hot seat ». A « hot seat » is when you share a specific problem and a specific question to the group. What is surprising is that we always see the same pattern that repeats itself. There is a person who shares a problem and a question and we see a lot of obvious things about the limiting beliefs of this person, how much that person has locked himself/herself into a part of the problem. From the outside, we see that there are other ways to attack the problem and we also see obvious solutions.

What’s interesting is that it seems extremely obvious for a person who is in the group to help find the solution but when you share your problem and your question, the group offers you things that you have never seen by yourself.

We all need a moment to take out our trash. We all need to share with a group what doesn’t work and what problems we have. Whenever we do that, we realize that we all have blind spots. Things that seem obvious to everyone but seem hard to see. It’s like seeing the flaws of another person but we don’t see ourselves our flaws.

Here’s an example, I’m ticklish. I can try to tickle myself, I can’t laugh but if someone else tickles me, I laugh immediately.

I can’t be at the window and see me walking in the street at the same time. So if you’re an entrepreneur and you feel isolated, break this situation. Go to events, try to meet other entrepreneurs because it will help you a lot.

You can’t know how many mistakes you make each day without realizing it. Only someone else can show you, your mistakes if you allow him/her to do so in a caring way. It’s not a matter of showing mistakes by accusing but in a kindly way to help you move forward. If you can participate in a mastermind group to be in a collective spirit of brilliant people, do it. It’s a great place to no longer be the smartest person in the room and learn new things to improve yourself.
