This happens to me, too... I'll have a problem that gets stuck in my head that I can't stop thinking about. In the car... making dinner... exercising... the whole time it's there, in my head, hanging over me. Sometimes to take my mind off of it I go work on other programming projects, but I am worried about burnout from programming 70+ hours a week. I've looked for other hobbies, but so far programming is the only one that I thoroughly enjoy and can stick to for an extended amount of time.
