I did a lot of theater in high school, and some in college. I think it had a significant impact on my writing and cartooning. My memory is not so great at memorization and I choose to allot my time to writing and drawing (and theater takes a lot of time), or else I would surely be doing it today.
And hey, might I mention that I have books for sale at the Topatoco Store? Yup, I just might.
