Walking to the Metro the other day, thinking about a problem, I caught myself saying, "What else?" to myself. Maybe it's a useful get-out-of-the-box method:

• What else should I be doing?
• What else could have caused this?
• What else could they have meant?
• What else is important?

And so forth. What else should be on the list?
