For an actor, you're rejected eight or ten times a day. All you've got to sell is yourself. You're not selling products, they're not turning down a car, they're turning you down. Most people can't handle that. Most people are essentially not set up that way.
That's one of the reasons I wanted to be an actor, to be like them. And there they were at my table, all talking about how nervous they were, about the lines, and so forth. No matter how big you get, you still have the same kinds of anxieties and so forth.
