I could not do what I do if I were not obsessive compulsive to a certain extent. I don't act clinically OCD. I'm not going to check things so many times I have to take drugs for it. But the kind of complicated and painstaking work I have to do to make my drawings, it just kind of harnesses that compulsive energy in a constructive way.

When I was growing up in the 1960s, there was starting to be more books geared towards young adults.

I do sometimes miss doing that lighter, more humorous work, and I find there's a heavier responsibility that goes along with a literary reputation. You have to start knowing what you're talking about and you have to go have public conversations with writers. That's been pretty intense; I have to really stay on top of things in a way I didn't before.

It's a hard thing to age a character because you can't really suddenly give someone gray hair.

I get to do for a living what I did as a child for fun, and that's pretty cool.

I love Jules Feiffer. I didn't discover him until I was a little older.

It certainly was an important moment for me, that realization that I was not going to get what I wanted. It was very freeing. I keep using that word "freeing" or "liberating." I feel like Houdini sometimes, like I'm just getting out of one set of shackles after another, hanging upside down inside a burlap bag with handcuffs on. Hopefully one day, I'm going to get out of this tank of water.
