Anything you write, even if you have to start over, is valuable. I let the story write itself through the characters.
I'm terrible at story and structure, but I'm not so bad at writing dialogue.
I never did improv professionally, but that was certainly in my training as an actor. I like it. Actually, when I did theater, I used to have a partner, and that was the way we used to write a lot of our sketches, through improvisation. So it's something I feel comfortable with.
I never had any master plan about directing, and I don't really write.
