One of the best memories of my life is contemplating that first finished drawing and realizing I had cracked the code, that I could make drawings like this whenever I wanted.

Every time I write something down I check it to see if it has that telltale glow, the glow that tells me there's something there. If it glows, it stays. Everything is either on or off.

To my way of thinking, the concept drawings that Rembrandt did, the drawings he made that he used to model his artists, to work out the compositions of his paintings: those are cartoons. Look at his sketch for the return of the prodigal son. The expression on the angry younger brother's face. The head is down; the eyebrow is just one curved line over the eyes. It communicates in a very shorthand way. It's beautiful, expressive, and, in a peculiar way, it's more powerful than the kind of stilted, formalized expression in the final painting.

The books that I do, the stories I write - I'm glad I'm able to do them, but they will quickly be swallowed up by the sands of time. Sometimes it frustrates me that I'm not able to do bigger, more important, more significant things. I guess you have to be content to do whatever it is you can do.

I have a personal definition of cartooning, which is, simply, "imaginative drawing." Anything you're drawing that is not in front of you but is a mental construct that you want to express in a drawing is, to me, a cartoon.

I could never write about the sort of people John Cheever or John Updike or even Margaret Atwood write about. I don't mean I couldn't write as well as they do, which of course I couldn't; they're great writers, and I'm no writer at all. But I couldn't even write badly about normal, neurotic people. I don't know that world from the inside. That's just not my orientation.

A mind in control is always better than a mind out of control. For one thing, a controlled mind can learn much better and go much further than a chaotic one. A person with a steady-state mind has the potential to exit this life with a much greater understanding than someone who is continually learning and forgetting, gaining and misplacing knowledge.
