Mine is a weird one: I started taking every other day off. Even as deadlines loom, I am committed to doing no work today. I can cook and read and surf the Internet and hang out on Less Wrong and chat with friends and take a nap and do art (but not art for my webcomic), but at all costs I will do no work. Tomorrow, I will do work (in my case, papers for school and art for my webcomic and editing some fiction), and unless something breaks the trend that's been working nicely for a week and a half now, I will do more work than I could have expected to do in three or four days before I started this. (I make exceptions for time-dependent things like class meetings.)

I have a few hypotheses for why this works for me:

• It prevents the low-level burnout that used to plague me. I can decompress from whatever heavy mental lifting I do regularly and for a large chunk of time.
• I actually enjoy most of my work when I actually do it, so obliging myself not to do it lets me get through the akratic aversion during my downtime. By the time I wake up on my work day, I've worked up a fair amount of antsiness about wanting to do something productive. Also, my creative ideas accumulate over time, not over effort; I have more interesting work-related ideas by the time I fire up Word when I've set the project aside for a day.
• I can goof off more efficiently. Instead of spending all day on Stumbleupon because I can keep telling myself "one more site and then really, I'll do something", I can read an entire novel or bake a cheesecake or watch half a season of Buffy the Vampire Slayer. These things require significant time commitments, so if I feel like I ought to be working I don't do them, but when I do them, they are more relaxing than the same amount of time in two-minute bursts spent obsessively refreshing Google Reader or checking my website stats or bothering people on IM.
