I think circadian rhythms are a crock. But I do think that sleep is an amazing brain-fermentation tool. I like to take a powernap (huzzah pzziz) at some point mid-day and I always notice an increase in my motivation, concentration, brilliance and boyish good looks after my mid-day slumber.

And, having done polyphasic sleep, I know that I'm able to excel on very minimal sleep -- so long as I'm getting enough REM cycles during the day. That is, I can excel so long as I stay healthy, otherwise I need all the recoup time I can get. But taking advantage of the amazing power of REM to increase my brain's organizational abilities is always a good idea. Which is why this very afternoon I shut my door, popped in my Shure e2c's, and lay on the floor for twenty minutes of shut eye. After that, I had another two hours of peak performance before I headed home to the Chaos Lab.

I'm all for early-morning productivity, when there's no distraction or interruption, but I'm also for getting another burst of energy and enthusiasm for a finish-line sprint.
