A little bit of everything, in my case; a list of the jobs I've had includes commercial salmon fisherman, movie theater assistant manager, comic book colorist, customer service rep, order processor for sales, data entry monkey for the Department of Health, and The Temp (AKA the guy who comes in for 3 days at Job A to make a billion photocopies for an upcoming lawsuit and then next week for 3 days entering sump pump data and then the next week for 3 more doing something else). And also lots of freelance design and writing for Dungeon, Dragon, and eventually Bastion Press, Wizards of the Coast, and Paizo.
