No one can be industrious all the time. My favorite procrastination tool?
It's a chain reaction game, and there's no skill required--just dogged perseverance. (Any pursuit that rewards obstinacy gets my vote.)
At first, I thought I was responding to the nice burst of color as the chain reaction takes place. But after playing the game about three months, I suddenly realized that the music for this game reminds me of the music from Thirtysomething. And that makes me happy. I'm not even going to pretend to be embarrassed by that.
