It goes all over the place, but here's what my best days are like:

8:30~9:00 wake up, stumble into shower

9:15 turn on computer, check email, do non-work

10:00 work begins

13:00 lunchtime!

15:30 shouldn't have brought a book! work resumes

17:30 ~ 18:30 creative impulse dies, work ceases for day

+ 1 hour go to gym

+ 2 hours eat dinner

+ 2.5 hours evening plans

22:00 ~ 2:00 AM read/game/movie/etc, check email, maybe write some goals down for later, go to sleep
