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.

Art - I had never thought of that as a career because it was like something I did so naturally, and it was fluid, and it is. And even though I still admire literature as the superior art form, I have to admit that art, for me, that's it; that's what I'm good at, and that's what I should be concentrating on.

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.

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.

If, for some reason, I cannot bear to work on something that needs to get done, I'm not going to force that. I'll just take a mental vacation. I think the best solution sometimes to working out a problem is to walk squarely away from it.

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.

The whole basis of working in black and white and grays became the basis of my understanding of color, because it's all about tone, it's all about light and dark. If you don't get that, then your color work is going to be a mess. So that's the beginning of the toolkit: drawing and black and white media.
