The challenge is to keep it fresh. If you're talking about Britney Spears over and over, it's very hard to keep that interesting.
I look to challenge myself with a character that's not like myself or anything I've done before, but I certainly don't reject roles based on how often I've done them.
Life is essentially a cheat and its conditions are those of defeat; the redeeming things are not happiness and pleasure but the deeper satisfactions that come out of struggle.
