On indies it's hard to do, but in rehearsals, you make mistakes in rehearsal. It's really hard rehearsing a play or what rehearsal you get on any movie. That's where you get to make your mistakes, and you make big ones. So when you shoot [the movie] or you finally get the play in shape and do it, the mistakes are out of the way. If you're not afraid to make mistakes, then there is no writer's block or actor's block.
