One of the glories of doing the book So You Want to Be President? was the shifts in tone, where I was able to be humorous and then very serious. And the impeachment page is certainly the best example of that. I didn't have to think too much about how to present this one. I got the idea right away that a good way of showing the shame of President Nixon would be to put him down in the shadows under the Lincoln Monument, with Lincoln sort of glaring down at him from an elevated, better-lit position.

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.

You have to get through periods of being blocked. Everybody has them. For me, they have everything to do with self-doubt. It's never a matter of laziness or inability. It's just a matter of believing that what I'm doing is worthwhile, that it matters.I just make myself work. I just make myself go to work, whether I feel like it or not.

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

My interest really is psychology, what's going on in people's minds as revealed on their faces and in their posture. That is my strength. And it's something that came from probably being a silent observer for most of my life and having to read what was going on in people's minds from only their postures or from their expressions.

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.
