Years later, when “Dilbert” was in thousands of newspapers, people often asked me if I ever imagined being so lucky. I usually said no, because that’s the answer people expected. The truth is that I imagined every bit of good fortune that has come my way. But in my imagination I also invented a belt that would allow me to fly and had special permission from Congress to urinate like a bird wherever I wanted. I wake up every morning disappointed that I have to wear pants and walk. Imagination has a way of breeding disappointment.
