Experience is very important of course, and the thing that's most important of all is to be true to yourself. To tell the truth to yourself and to everyone else, that's very important.  Because that's what improvisation actually is about. It's about saying what the truth is about your feelings and about your experience, and about what it is that you can do and what you can't do. The thing that improvisation does for me, it makes me realize that I don't have to feel bad about the things that I can't do, but I have to admit it. Because then it's an advantage to me. If I try to make myself believe that I can do things that I can't do, I'm being a disadvantage to myself. And improvisation is like that. It makes you admit the truth about yourself. The good and the bad. There's plenty of bad.
