Comics are not illustration, any more than fiction is copywriting. Illustration is essentially the application of artistic technique or style to suit a commercial or ancillary purpose; not that cartooning can't be this (see any restaurant giveaway comic book or superhero media property as an example), but comics written and produced by a cartoonist sitting alone by him- or herself are not illustrations. They don't illustrate anything at all, they literally tell a story.

Storytelling is one of comics' esthetic hurdles at the moment, which was the novelist's problem 150 years ago: namely, to take comics from storytelling into that of "writing," the major distinction between the two to me being that the former gives one the facts, but the latter tries to recreate the sensation and complexities of life within the fluidity of consciousness and experience. As far as I'm concerned, that's really all I've been trying to do formally for the past decade or more with comics, and it's certainly time-consuming, since it has to be done with drawings, not words.

As I get older I find myself thinking about stories more and more before I work so that by the time I eventually sit down to write them, I know more or less how it's going to look, start or feel. Once I do actually set pencil to paper, though, everything changes and I end up erasing, redrawing and rewriting more than I keep. Once a picture is on the page I think of about ten things that never would have occurred to me otherwise. Then when I think of the strip at other odd times during the day, it's a completely different thing than it was before I started.

My mother was always encouraging about my wanting to be an artist.

Sometimes I get worried I'm getting too caught up in the nauseatingly oily smoothness of my own line, when all I'm trying to do is make it as clear as possible.

Comics is different than writing because when you draw something you are trying to visualize it and you are trying to put yourself in that space. And when you're drawing something, all sorts of associations come up in my mind that I never would have thought of otherwise.

I do worry that beginning cartoonists could feel somewhat strangled by the increasing critical seriousness comics has received of late and feel, like younger writers, that they have to have something to "say" before they set pen to paper. Many cartoonists feel even more passionate about this idea than I do, vehemently insisting that comics are inherently "non-art" and poop humor or whatever it is they think it is, but that attitude is a little like insisting that all modern writing should always take the form of The Canterbury Tales.
