I don't know what acting is, but I enjoy it. I think we ask too many questions of ourselves. We make too much importance of stuff. But I do say to actors when I have taught in classes, or when I sometimes do a talk to a group. I'll say, “If I never acted again, the world wouldn't stop, nor would it stop if I didn't stop acting. That's how important it is. I know it [seems] important when you're young. But I say, “Lighten up. Don't take it all so seriously.” All the gurus and teachers will take your money and run.
Some nights you might go through an entire performance and not feel a thing, and the audience may have a much better time, 'cause if you're enjoying yourself on stage too much, they're having a terrible time because they can't hear you. And if you're a woman your mascara's running.
I never make conscious decisions. If my agent says to me, "It's a good script," I'll do it. I don't plan. I've got a lot of things to do. I'm at the roulette table and my luck seems to be running at the moment. I might as well stay there until it runs out.
