Really, most of us just focus on what's in front of us. We're too busy putting out the fires of everyday life.
Life is hard for everyone. That's why there's such a nice reward at the end of it.
Genetics play a huge part in who we are. But we also have free will.
I'm not particularly a career-oriented guy. I'm lucky. I can make really interesting films much of the time with interesting people yet be anonymous, have a private life. But, I'd like to have the choice of the better roles.
My thing about looking good is that it should be the character. If I'm playing a character who's concerned about his body - an athlete, say - I'll get in shape. If I'm playing a character who doesn't or wouldn't, I don't. I almost never get in shape for a movie, even though I know it would be a good career move.
