I came across this article
The population is split pretty much evenly between introverts and extraverts
But why I found most people like to identify themselves as outgoing and extravert. Liars??!!
That could be because Corporate America is biased towards extroverts. I'm an introvert but lots of people see me as extrovert.
After so many years in the corporate world I learned how to act. You have to be out there all the time, promoting yourself at work. The right people need to know your face and name. Work results by themselves are not enough.
I always make small chat at the coffee machines at the office, make jokes, compliment ladies on outfits, etc.
Introvert, extrovert is about how you get your energy, how you recharge your batteries.
An introvert needs time by himself/herself to recharge.
An extrovert draws his energy from others.
It is not really related with shyness. I know many extroverts that are shy.
I'm much better at social interactions than my best INTJ friend for example. I being an INTP. That is because I moved from IT into Marketing. I put myself out there. He's never moved from his IT corner and doesn't have much social stamina.
Thus, in conclusion, I believe you can't change how you recharge yourself but definitely you can change how you act in social situations.
