If you're in this business, like any high-stakes business, the highs and lows can make you a manic-depressive person, if you weren't that way to start with. 'Cause it's just so crazy on your psyche. A lot of it has to do with people thinking they're greater than someone else.
I have a friend who says the best boyfriends are ones with intimidating, good-looking older brothers. The boyfriends try harder because they're so insecure. Maybe I'm the female equivalent.
