Great post on an interesting topic. I thought I was an extreme extrovert all my life, and then suddenly I got to know myself better, and I think I am leaning more towards an introvert actually. I am talkative and outgoing, but I really need a lot of time alone and I get stressed out when there are too many people around. I also think my personality changed a lot as I got older. I used to love having as many people as possible around me, now I'm quite the opposite.
