There's a certain state of mind I find myself in sometimes, where I'm not getting any work done, I'm not getting any sleep in, and I'm not particularly having much fun or even relaxing, and, by my definition, I'm wasting time. Basically procrastinating, reading sites, sitting around, it's icky.
So what I did is I made a list over a few weeks of all the little tiny things that contribute to getting me in that state, and the actions I can take to reverse them. My list has a few categories with things such as brushing my teeth, cleaning up my desk, stretching, bathing, organizing a list of tasks for the day, using the bathroom, getting proper nutrition. All of these things are incredibly mundane, but they're very easy to forget, and not doing them contributes to that feeling.
What I do when I'm feeling all nasty like that, or any time I need to get work done, is I flip to that page in my pocket moleskine, then get out a post-it note and copy down all the items that are relevant. Usually there are a small handful of em, and it'll take me about fifteen minutes to get in a nice state where I can approach my work comfortably.
The trick here is that doing any one of those items on the list doesn't do a hell of a lot. But in a ten minute dash, suddenly my desk is clean, I've organized my list of tasks, I've changed from the clothes I've been wearing all week, and I've got a nice cold soda. It feels good, because there's a good chance that most of those things were subconsciously bugging me.
