I guess some of those things apply to me, I am an ACTUAL artist, work well alone, one hell of a problem solver and am very mechanically inclined.... but I love to socialize (once im comfortable, I just usually can't find a good way to start a conversation unless im hitting on someone

). I do have a very analytical brain and absorb the idea of my surroundings quickly, and then feel the need to move on... but dont mind lingering if I am comfortable with a few individuals... The part about the few close friends I have is pretty accurate, though I am a social butterfly (Thank you Facebook for making meeting people so easy for us introverts). I value my few close friends and bend over backwards to make sure they are ok- a doormat at times, but it is mutual.
Is it possible to be only partially introverted? Or is it just that I have learned to use my desire for company push me past the feeling of awkwardness...
BTW just a side note, being considered 'attractive' does seem to help me with talking to others because alot of girls start conversations with me before I even have to try
