With acting it's your neck up there in the end. And if you think the director can't help you it's one thing. But if you feel they're reining you in when they need to be giving you some rope, or vice versa, then I just don't tolerate that.
Sigmund Freud said we act out our own dreams, but if you are only an actor you are not acting out your own dream. You are simply participating in someone else's dream.
It's not a field, I think, for people who need to have success every day: if you can't live with a nightly sort of disaster, you should get out. I wouldn't describe myself as lacking in confidence, but I would just say that the ghosts you chase you never catch.
