Think of all the really successful men and women you know. Do you know a single one who didn't learn very young the trick of calling attention to himself in the right quarters?
One of my favorite episodes was the one in which Homer grew hair. That was a very unique episode, since there was a gay secretary, but that wasn't even the issue of the show-the issue was Homer's image changing because he had hair.
I always get bored with my hair. That's why I would always change it throughout my career.
