Here's a mildly interesting article. He says basically that one should procrastinate by doing slightly less important things than whatever is the most pressing deadline. Thus you're procrastinating, but still getting useful work done.
Structured Procrastination
I think it somewhat hits the mark. During this past school year, when I had many projects on the go, I would often procrastinate by working on my thesis research instead, which isn't really due until 2007. And, when I'd finally finished all but one of my course projects, I was far less effective at the one that remained, because I only had the one thing to do, and thus procrastination meant doing nothing whatsoever. Similarly, a girl I know has often claimed that she is most productive and successful when she has a million things to do; I viewed this claim with great skepticism, but I'm starting to think there might be something to it.
Then again, this method requires you to enjoy your secondary activities and that they be useful. Watching Bond movies and replays of Warcraft games might not be as effective.
