I moved to Chicago in the early 1990s and I studied improvisation there. I learned some rules that I try to apply still today: Listen. Say yes. Live in the moment. Make sure you play with people who have your back. Make big choices early and often. Don't start a scene where two people are talking about jumping out of a plane. Start the scene having already jumped. If you're scared, look into your partner's eyes — you will feel better.
