"I haven't really lost faith in my work - other than for quite short periods when the work is harder than usual - but I have hit points where I want to quit because cartooning is just too hard, too demanding an art form. Basically, there's nothing to be done about that but to keep going (if you're in the middle of something), or stop for a while and do other things while you wait for your motivation to return."

I think you have to keep going. Otherwise, you know these fellas that say, "Boy I can't wait to retire. Boy, I'm going to be 65 years old, and I'm retiring and I'm quitting and that's it." Well, two weeks later they're saying to themselves, "What the hell am I gonna do?" And first thing you know they find themselves in a wheelchair or in a rocking chair going back and forth, back and forth, and that's the end of it. And suddenly you're dead.
