If you are one of those people who have trouble of digging out of messy areas (and you aren't in the construction business), you may want to check out FlyLady.net. The site is dedicated to helping people learn new cleaning habits and generally ridding themselves of clutter.
Here's the latest tip: "Your new habit for October is to spend 15 minutes each day dealing with paper. You can break it down into 5 minutes three times a day ordo 15 minutes at one time." After this, you are supposed to send an email to FlyLady, but there's no word yet how to attack that ever-growing email inbox.
