So much this. As I've gotten older, instead of working half the night on a difficult end-of-day problem that I'm stuck on, I just set it aside at the end of the day and by the time I start back up in the morning, I've got a good idea how to solve it.

Does it mean THAT problem gets solved later? Sometimes, but often not. And more importantly, I'm maintaining a pace that's SUSTAINABLE. I can crank on hard problems almost constantly, but I leave myself some space so I don't get burned out.
