notes to self

Do not smash your head against a problem for consecutive hours. Instead:

• Ask for help. It doesn't matter whether you ever send the request; in the process of putting the problem into language, you're more than likely to solve it. (Yes, I know: "Pair programming!", you say. But I'm all alone here.)
• Stand up and walk away. Do not touch anything resembling a computer for at least ten minutes.

Will someone please remind me of these next time I get stuck?
