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.

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 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.

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.

I do keep up at night. I try not to let my mind go to extremes in the middle of the night because it would be better to turn all that stuff into dreams; it would be better if I was sleeping, because dreams become good metaphors for what's really going on inside of you.

I feel that if I had not had an art program in my school, I would have failed in a big way. My teachers knew I was intelligent, but they didn't quite know how I was ever going to apply that intelligence. The one or two teachers who knew me well knew that it would be through drawing or acting or whatever means of expression I was allowed.
