By the time that book So You Want to Be President? came along, we had already had enough presidents that had shown us that presidents are human beings. So I felt I was contributing to the common knowledge there, but not revealing anything really new - sort of supporting what everybody already was suspicious of.

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 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.

Humanization and coming to understand somebody as a human being is about as good a kind of forgiveness as you can get, I think.

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me again, that woman who was totally incapable of giving nurturing to anybody, and, you know, her selfishness and her withdrawn indifference to everything but her own needs.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 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.

What I try to do in my picture books is to be all-inclusive, but not exclusive, to not exclude the kid and not exclude the parents from the experience. And it's not a very easy task; you can't find stories that work that way too much of the time.
