Here is one important and interesting one:
Produce the show. Anywhere. Anyhow. Produced shows have more value. I don't care if it was up at a community theater, a black box on the lower-east side, or in your college dorm room. Get it up, and tell me that it was up, and show me some good reviews. A few random quotes from a Philadelphia paper is what got me interested in the book writer of Altar Boyz's work. Without those quotes, he and I never would have met, and the show wouldn't be the same.
