There is a myth that extrovert people are better in business and that they are better sales people.
Is it true though? Let us take a quick look at this.

For a very long time, I had the perception that being an introvert was a weakness, and that if you were to make it in business, be a good sales person, a good leader and a good speaker, you had to be an extrovert. Because of this, I would always tell myself (and others, in various personality tests, interviews, etc) that I was an extrovert. It is only in recent years, that I have come to learn that I am really not an extrovert. At best, I might be an Ambivert – which is what you are when you are in the middle of the two.
