Place an empty moving box near your door to collect items bound for Goodwill. Every time you leave your house this month, place one item in the box.
2. Cold Cut
Open your fridge. Spend five minutes disposing of week-old takeout containers, expired condiments, and smelly milk.
Challenge yourself to find five trinkets or decorative items that don't fill you with joy when you look at them. Put them in your Goodwill box.
4. The Third Degree
Chances are, you wear only what's near the top of your piles of T-shirts and sweaters. Put the bottom third of each pile in your donation box.
In the next five minutes, find five items in the room where you are sitting to give away, five to throw away, and five to put away. Ready...go!
6. Inspector Gadget
Spend 15 minutes unearthing electronics you no longer use: e-readers, game consoles, cameras. Sell them for cash using eBay's new valet service, Sell for Me.*
*Ebay's new Sell for Me program will send you a free box (or boxes), which you can fill with items worth at least $50 in excellent condition—designer clothing, appliances, collectibles—and send back, postage free. Valets will sell your haul; you'll get 70 percent of the sales. In certain cities, you can arrange for a truck to come to your home to collect your items. Visit Ebay.com/SellforMe for more information.
7. If the Shoe Sits...
Gather your family's worn-out sneakers and drop them at any Nike or Converse store; they will be shredded and turned into playground surfaces and turf fields.
Go to your car with two bags. Use one to collect trash and the other for anything else that doesn't belong there, from mail to kids' toys. Return these items to their places.
9. The Reckoning
Walk into your hall closet. Identify five things that both you and I know you're never going to pull out again (old ski parkas, broken umbrellas). Donate or trash.
10. Pulling Your Weight
Weigh each family member. Now give everyone ten minutes to bag things they own to give away. Weigh everyone again; whoever has "gained" the most weight wins.
11. Company's Coming!
Pretend dinner guests are arriving in 30 minutes. What would you tackle first: the dirty dishes, the toys strewn everywhere, the pile of shoes in your entryway? Now tackle it.
12. Minute to Bin It
Dash madly around your house for one minute collecting old magazines, newspapers, catalogs, party invitations, and paid bills. Recycle or shred them.
13. Sock It to Me
Empty your sock drawer onto your bed. Put the pairs you actually wear together and return them to the drawer. Use the rest to make cleaning rags.
14. Single File
Open your file drawer and identify your least organized folder. Now spend 15 minutes making it your most organized.
15. Seven Minutes in Hell
Go to the messiest room in your house and set a timer for seven minutes. Now put things away, make piles—and keep moving! Break that mental barrier! Get started!
