It's purely a job. in that I leave the work at the door when I go home, and that's a very odd feeling, let me tell you...

Cool, I think those are the best kind of day job. I recently quit mine to write full-time because I couldn't leave work at work anymore, and it was making me crazy. It's been really interesting to see how much more I get done without having to start out the day with a huge cup of stress.
