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.

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.

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.

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.

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.

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

There are just certain things you can't talk about with kids. I just totally do not believe in this sort of Bart Simpson character who infects so much of our literature and film and TV stuff nowadays, these know-it-all kids who seem to understand the hypocrisy of the adult world so thoroughly and can talk about it with such articulateness. That's bunk. Kids are kids; they're innocents, they really are. For a long time, no matter what they see, no matter what they're exposed to, they can't get it until they have developed enough.
