I'm currently in the middle of what I will call, for lack of a better term, a time audit. At the suggestion of the Austenite, I've created an excel file that has a running tally of every hour (it's actually accurate to five minutes, sort of) of my day. During the past three days, I've spent around 25 hours at work, 21 hours asleep, and close to 9 hours have been marked as "social," which basically means sitting around talking to roommates and/or watching movies with folks. I've spent between 2 and 3 hours each on exercise, computer time, and bathing, with service taking the smallest chunk of time at an hour and a half. I'm kind of adding categories as they come up, and although I had kind of planned on needing a "sinning" category for the hours I couldn't figure out what I was doing during the day (and thus must obviously have been sinning) I have so far been pretty good about marking stuff often enough that my time is all accounted for at the end of each day.
I'm kind of looking forward to analyzing everything at the end of the week to see what I can improve on (prediction: sleep more, spend less time on the computer). I was recently listening to an old This American Life about a guy who makes lists and tallies of everything he does every day for the past like 40 years, and I thought, "gee. I could be that guy, except I'd have statistical data for how long I did stuff for!" Obviously I need more sleep.
