This is a great article from Huffington Post that seems to validate that I am normal in most of my abnormalites. While J. Randy Taraborelli is specifically referring to Michael Jackson, I think the words reign true for most creative people.
“Creative people tend to be both extroverted and introverted. We’re usually one or the other, either preferring to be in the thick of crowds or sitting on the sidelines and observing the passing show. In fact, in psychological research, extroversion and introversion are considered the most stable personality traits that differentiate people from each other and that can be reliability measured. Creative individuals, on the other hand, seem to exhibit both traits simultaneously.” – J. Randy Taraborelli, Michael Jackson biographer
