"I have bad days. Sometimes I have a lot of bad days. By and large, I think most people fall into a bad mood because they're able to ruminate on whatever the problem at hand is, and that makes it worse. But when you intercept the rumination process with something that requires your full attention - that's stimulating and absorbing, that places a demand on your intellectual focus - you don't get to ruminate. In a way, it's a mental health aid to be able to do that so much. My routine, what I do, it just feels like home. It's my comfort food."
