In life most of us are highly skilled at suppressing action. Bad improvisers block action often with a high degree of skill. Good improvisers develop action.

The best laughs are on the recognition of truth.

The improviser has to understand that his first skill lies in releasing his partner’s imagination.

Many teachers think of children as immature adults. It might lead to better and more 'respectful' teaching, if we thought of adults as atrophied children. Many 'well-adjusted' adults are bitter, uncreative, frightened, unimaginative, and rather hostile people. Instead of assuming they were born that way, or that that's what being an adult entails, we might consider them as people damaged by their education and upbringing.

If it weren't for fear, I wouldn't have to teach you a damn thing

Enjoy things even when you’re screwing up.

If you have a good idea, open your mouth and say something else.
