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.

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

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.

I don't know if I ever would have developed into a good actor, but that got completely scotched when I lost my vocal cord at 14 in the operation. But writing always - writing plays, writing, writing, writing, that was what I wanted to do.

Even though I have this solid career in picture books, I've not only been thinking about kids - because I don't think that much about children; I'm not a child educator; I'm just a former child.

I used to teach on a college level, and I've taught in schools where kids just wanted to be artists, and I used to be furious with them if they didn't read, because they just seemed so - their education seemed so thin if all they could do was pick up a paint-loaded brush and fling it at a canvas. I mean, there was nothing to express there, except maybe their own personal feelings. But if they're not - if they don't have a grounding in the way these things have been expressed by other people down through the centuries, then they're lost.

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.
