I have had great success with a small filing box, perhaps the size of a backpack. I toss half-important documents in there (vehicle service records, key receipts, contracts) and forget about them. Every couple of years I spend ten minutes flipping through. Documents that are laughably obsolete are promptly tossed, and the box goes back into the back of the closet. Perhaps an important circumstance is how little paper I deal with, though. There is no temptation to file all my bank records, for example, because they are already all electronic.
