I spent a few years cleaning hotel rooms and, in hindsight, I did some of the best programming work of my life during that time. In part because I would find insights into a problem by analogizing it to cleaning hotel rooms (many of the fundamental problems are the same, just in a different context), and in part because cleaning rooms is mostly automatic, physical, mindless work and it bought me 8-10 hours a day where I could just think about whatever I was working on at home. That taught me the value of letting your mind "wander" into solutions when you can't reason into one.
