It's a good video that addresses a lot of misconceptions. I do believe I'm an introvert, but I also see a lot of people greatly misunderstanding introversion/extroversion.

One part of the video that really hit home for me is the part where he talks about having a purpose. I can speak in front of large crowds because I'm there with a defined purpose, whereas I've never gotten used to small talk. This became really obvious back when I was in a band. People would talk to me after the show at the table and assume I was the same person I was during our performance, whereas in a way that was just a role I played, but it was comfortable for me because I was there with a purpose. It's not this alone that defines introversion/extroversion, but I feel like a lot of people could benefit from understanding this. It's why most of the friends I make are centered around shared hobbies and interests.

I usually don't click YouTube links, but this was good.
