Seth Stevenson's "Letter to a Young Procrastinator" (Slate, May 12, 2008) makes an interesting suggestion.
Stop resisting and embrace your procrastination. Don't agonize in front of a blank computer screen. Don't sit around for hours—intending to start your work any moment now—only to find that in the end you've accomplished zilch, save for ruining your own day.
You could instead, for instance, work on a small, tangential aspect of the assignment. Some weird take on things—one that doesn't make you miserable. This may be of little direct application, but there's a chance it could also pay off, kick-starting a new line of thought or adding nuance to your final result.
There's obviously a bit of irony in his tone, and I am, to be sure, not recommending this approach, but there is something about the idea of not putting off your procrastination til tomorrow and getting it done today that appeals to me.
