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.
I think theatre is by far the most rewarding experience for an actor. You get 4 weeks to rehearse your character and then at 7:30 pm you start acting and nobody stops you, acting with your entire soul.
You can fake your age or mask it, but the passion that moves the characters has to be real.
