Leaders of the world, my message to you is simple: to achieve universal peace and understanding on this planet you have only to speak plainly, even though you may look foolish. This is a thousand times better than looking good and talking nonsense.

I open journal, I look at the picture and I remember where I was. And I remember the time of day, the temperature of the air, what music was playing, or who was talking to me, or who was looking over my shoulder and what conversations we had and the smells of the earth and the time of year it was. It's all there for me in a way that we don't get looking at a snapshot. Most of us look back at a snapshot from ten years ago and say, where was that? We don't even remember where we were.

I began drawing probably when I was - around the same time everybody else puts a mark on a piece of paper with a crayon - when I was two, probably. The difference between me and everybody else is, I kept doing it for the rest of my life; there was something very satisfying about that.

Teenagers are always sneaking around in drawers where they shouldn't go and reading things they shouldn't be reading. And that's an attempt to try, I think, to penetrate, that's how I found out as a teenager what was going on, was by sneaking into drawers and reading letters that I had no business reading.

Even after the age of 50 it was impossible for me to see my mother as a human being. I felt she was a monster, and she had subtly been influencing my behavior and my thoughts and my dreams for so long that she was kind of a monster; she was a demon. And when I brought her back to life, I could feel that malevolent presence around me again, that woman who was totally incapable of giving nurturing to anybody, and, you know, her selfishness and her withdrawn indifference to everything but her own needs.

I found great value in teaching students from the outset of their studies how to draw very realistically. Otherwise, you're starting deep into the alphabet instead of having started at the start. If you discard essential things like drawing, design, color and so on at the beginning, then you're just sort of floating out in space, without any basis to work from.

I think drawing is really the basis of all art, even sculpture, film. The greatest filmmakers have always been able to at least roughly sketch out their ideas in storyboards. And black and white in particular is a good place to start.
