The fact that maybe I had some success playing G'Kar doesn't guarantee me three years later that I can still do it, so I have to keep my senses alive and still be working on it.
People come into public life for different reasons. None of us are ego-challenged, I think, or we probably wouldn't be doing what we're doing, so if anyone tells you that they don't like the sound of the applause and the ego gratification, I don't think they're being straight with you.
Luck? I don't know anything about luck. I've never banked on it and I'm afraid of people who do. Luck to me is something else: Hard work - and realizing what is opportunity and what isn't.
