I find that after throwing myself at a problem too long, I have a hard time approaching it differently from how I've been approaching it. Sleep seems to reset my mind. If I approach the same problem after waking up, I come up with a fresh perspective. On the other hand, if I'm "in the zone" before I go to sleep, I wake up and it's gone. I think that also explains my tendency to stay up till 7AM... need to take advantage of the productivity boost while it lasts.
