Advice From the Creator of Calvin and Hobbes
The cartoon is from and the advice is from Bill Watterson.

For most of my life I went from job to job doing what I had learned to do in order to have that job and pay my bills. It's never been a rewarding feeling at all but rather, a necessity.

Then I started Autcraft and even though it never paid my bills, it has been the most rewarding thing I've ever done. I'm still struggling to make it work and there are still people who think I should be doing a job rather than "playing a video game" but in the end, what I do with these kids has greater value than anything else I've ever done.
