Oh, I didn't mean I shut my laptop off for the duration of 9 to 11. I meant "I shut it off not after 11, and closer to 9 if possible". This actually ends up taking up about half an hour. It nets me lots of time, really, because it makes it easier for me to go to sleep, which makes it easier for me to get up at a regular time, which makes me far more productive while I'm awake. So less of the time in my day is wasted on being inefficient.
