Good improvisers seem telepathic; everything looks pre-arranged, This is because they accept all offers made—which is something no ‘normal’ person would do.

In a normal education everything is designed to suppress spontaneity, but I wanted to develop it.

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.

None of us really grow up. All we ever do is learn how to behave in public.

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.

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.

The improvisation had to be in public, because you only get value playing to strangers.
