I found this helpful hint in the TeamSugar group Housecleaning Support Group. It makes so much sense, don't you think?
"Pare down. The less you own, the less you have to clean. Get rid of everything you don't love or need. Can't decide whether to ditch it or not? Put doubtful items into a box, tape it closed, and mark it "Deliver to [name of favorite charity] on [date six months in the future]." (Seasonal items should be earmarked for disposal in a year's time.) If you haven't had any reason to look inside the box when the "deliver by" date arrives, dispose of it. Do not under any circumstances take a last peek inside."
