I have a clutter problem in my home, but it isn't paper (other than magazines which I allow to accumulate some before giving away). Mail is sorted as soon as it's brought in and all junk is discarded immediately. I only get two paper bills a month (all other and bank statements are online), so most of what I do get is junk, magazines I subscribe to, or catalogs of some sort. If it's a catalog I want to look at, I give myself a week; at the end of that time, it is trashed even if I haven't looked at it yet.
