What methods do you usually use to keep track of stuff like this? I can well believe that documenting my calories, sleep, exercise, work, etc. would more than pay for itself in terms of hours and dollars, but I'm a little concerned about the upfront willpower/morale investment...I'd feel a little crazy keeping such rigorous track of what I'm doing, and it would help me overcome that feeling if I knew, in detail, what somebody else had done and why/how it worked for her.

I'm especially curious as to whether and how you make any effort to measure the quality of your hours/calories...if you work an hour while distracted, do you count that the same as if you were focused? If you sleep an hour from 10 am to 11 am, do you count that the same as if you sleep an hour from 2 am to 3 am? And so on.
