> I noticed when I focus for 3-4 hours on some tough problem, then interrupt and do something completely unrelated or sleep, I get surprisingly many ideas quickly leading me to a solution. If I just sit in front of a monitor, it might take a week to solve the same. Weird, but works for me. Oddly, I have almost this exact same experience. If I work on a tough problem for 3 or 4 solid hours and then either do something completely different or go to sleep, I usually come back with at least three or four plausible solutions. There's a 50% chance that we're both weird and a 50% chance that you're onto something....:)
