>I find something else to do for a while - a day or two - and let my brain fix the problem in the background. When I get back to it, it's almost as if I had a new pair of eyes. I see it differently and then try a different approach. Also, the principle of Auntie Emma helps - by either trying to explain your problem to a colleague, or trying to document it, you push it through your head in a different way and thus see things you didn't see while you were alone with the problem in your head.

Often getting up and walking to get a bit of water would allow me to solve a problem. Many software developers I know have a joke about waking up at 2 AM and having the solution to a problem. That is too real for many people. Your suggestions are good and I hope that others follow them.
