_"Pick one task around your house that needs doing that is small and can be done in short order and go take care of it."_

Doing the dishes is a good one. It doesn't take all that long, it gives you time to reflect as it rarely requires great attention, and, even in a dwelling that is habitually cluttered, a moderately clean kitchen will make it seem like you have accomplished something.

Doing the dishes/cleaning the kitchen is my number one low-tech way to feel better about myself and my surroundings. (With the added benefit that my wife greatly appreciates it, since she can relax and watch video clips on her iPhone.)
