Accept the other player's reality. Ours is a theatre in which every decision is relevant, ecological, holistic. If the whole is to be art, the parts must strive not to be. Always take the active choice rather than the passive choice. Ideas reveal more in action, rather than idea to idea.
Action begins with the disruption of a routine.
Move action forward, not sideways or backward. Keep the action on stage. Don't plan the future. Don't bring up the past. Don't focus on people who aren't there.
