I tell people not to do their best. I don't know when that started. Quite a while ago. Because I . . . when they're doing their best I don't get their best. So I try to persuade them to be average. Because if you're wonderful and you're average, you're still wonderful. If you're a bad improviser and you're average, you're what you are.

I mean, in the foreword to Impro in Denmark is by Søren Iversen, who I taught long ago, he was a Danish director, after he left. He said he'd read about [Eugeny] Vakhtangov. I'm a fan of his. When he heard that Vakhtangov had lots of tricks, he thought this was very bad. But when he came to be my student, he realised it was very good to have a lot of tricks. You saw some this morning.

Most people I meet are secretly convinced that they’re a little crazier than the average person. People understand the energy necessary to maintain their own shields, but not the energy expended by other people. They understand that their own sanity is a performance, but when confronted by other people they confuse the person with the role.

There are people who prefer to say ‘Yes’, and there are people who prefer to say ‘No’. Those who say ‘Yes’ are rewarded by the adventures they have, and those who say ‘No’ are rewarded by the safety they attain.

Enjoy things even when you’re screwing up.

As I grew up, everything started getting grey and dull. I could still remember the amazing intensity of the world I'd lived in as a child, but I thought the dulling of perception was an inevitable consequence of age - just as a lens of the eye is bound gradually to dim. I didn't understand that clarity is in the mind.

You can sort of trick people into being really good. Even if they didn't know anything.
