Challenge Your Intelligence

brain scan

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.

Navigate In Tableau

front boat

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

We’ll explore Tableau’s tools

From the connection manager, we’ll go into the Tableau’s workspace.

Click on the « Sheet1 » tab at the bottom of the window.

Here is the Tableau’s workspace.

The 2 important elements of the workspace are « Data » on the left and the workspace on the right. It’s in the workspace that you’ll create tables and charts.

We’ll start with « Data » on the left.

« Data » divided into 2 zones : dimensions and measures.

The dimensions and measures are 2 different rules that will allow you to manipulate data.

Tableau sets the numerical values in « measures » and the categorical or quantitative variables in « dimension ». This is the Tableau’s settings by default.

There is also another way to explain « dimension » and « measures ». The « dimensions » are independent variables and the « measures » are dependent variables.

For exemple, « Units » is a measure, it’s the number of items sold per product. « Region » is a dimension, it’s the geographic region where the product sold. With 2 elements we can know how many items sold by region. This means that « Region » is an independent variable and « Units » is a dependent variable because it will be grouped by region.

But if you don’t like it, you can move the entities between dimension and measures and the opposite by click and drag.

In the menu bar, at the top, there is « File » where you can open and save file.

« Data » to connect to new source files.

« Worksheet » is the workspace to create analyzes

data science tableau screenshot

« Dashboard » is a combination of worksheet

data science tableau screenshot

« Story » is a combination of worksheet and dashboard

data science tableau screenshot

« Analysis » to specify how you want to do your analysis on your workspace

data science tableau screenshot

« Map » to add maps to the workspace

data science tableau screenshot

« Format » contains formatting options

Now, let’s study the workspace.

In the workspace, the main elements are « Columns » and « Rows ». This is where you decide which data goes in columns and rows in your worksheet.

You can also choose different format for these elements like colors, size, text level of detail and tooltips (useful tool optional).

Let’s do a test. Use data from « Region » (which is in « dimension »). Move « Region » with a click and drop to the center of your workspace. Now, « Region » is in the element « Rows ».

A table appears in your workspace.

You put a dimension in your workspace. Now put a measure in your workspace.

Uses the « Units » data. Move « Units » with a click and drop next to the « Region » column.

data science tableau screenshot

As you can see, Tableau automatically put « Region » in the « Rows » element and the « Units » data aggregated by region. In this way, you can tell how many items were sold by region.

Now, what you can do is to move « SUM(Units) » to the « Columns » element.

And then, you have a « bar chart » to see how many items have been sold by region. You can enlarge the graphic with a click and drop.

Let’s look at the tools that are in « Show Me » zone.

data science tableau screenshot

Click on « Pie chart » to have this chart’s type.

data science tableau screenshot

Click on « Size » icon and drag from left to right you can increase the chart’s size.

In this chart, each region has a color and proportion of items sold by region.

You can also test the « bubble chart ». Tableau organizes the data automatically and everything and placed in the « Marks ».

data science tableau screenshot

You can test « Treemaps » chart. This is the same principle as « bubble chart » but it’s rectangles instead of circles.

data science tableau screenshot

As you can see in « Show Me », there are charts disabled. This is because you need some elelments in your data to be able to activate them.

For example for the « Area chart », you need « date »data to activate it.
