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.

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.

My friend advised me to go into studying art, which at first shocked me because art was so easy. It was just something I did, like breathing or brushing my teeth. It couldn't be a job. I had a much more difficult time writing plays, making myself sit at that typewriter and finish those things.

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.

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.

Writing stories, adopting other characters, making up fantastic stories and tales, this is a way of perhaps enhancing who I am. Writing stories takes a commonplace old life and makes it all somehow more interesting. And hopefully I can do that in a way that touches a lot of people in their lives, too.
