Oh that TED and that book are excellent. I am an introvert much to many peoples surprise.
On Thursday at a course I am doing we all did the Myer Briggs. I landed INFP as I always have (I've done it three times now, twice in half day workshop context - wasting tax payers money working for gov). Anyway, this woman on Thursday mocked me, called me out "you???!! You an introvert " rah rah. Was embarrassing. For her mainly. I stated I was an introvert who has learned to live in an extrovert world. Then As a dig I added that being introvert / extrovert has less to do with how much and how loud you talk that extroverts probably realise. Then she told me I need a few drinks In me. Urgh. I muttered " I don't drink. But you might lead me to smoke crack to get through this course".
Anyway, I am taking that book in on Tuesday for a guy I was telling about it. Highly recommend.
I am an introverted exhibitionist. Makes people think.
