I love MBTI! ENFP, with a strong T side. N is just dominating, it's both a strength and a weakness.
I think some people are getting the wrong idea about the introvert/extrovert split. It's not whether or not you're popular, or loud really, the only real defining question you should ask is if you like crowds. An extrovert likes the buzz of having a lot of people around them, it gives them energy, whereas an introvert often finds that too scattered and prefers a small group of friends.
It's not a cool guy vs loser split either (at all), there are many benefits to being an I. It's easier to focus as an I, to reflect, because the primary mode of interaction for an I is intraspecting. I find that our schooling system is really geared towards an introvert with lots of textbook knowledge, and hence it's kind of weird that society often sees introversion as a bad thing. I feel sorry for I's really, it really isn't fair sometimes.
ps. lol Stath, I pinned you on that while we were chatting like a year ago. Ohhhhhhh yeeeeeeeeeeeeeeeaaaah~~
