In 15 Minutes I...
1) Put all the toys away.
2) Cleared all the flat surfaces: top of entertainment center, tops of end tables
3) Re-tucked slip covers
4) Sorted through our newspaper basket. I pulled out coupons to clip and took everything else to the recycling bin in the garage.
In main living areas it's helpful to take an empty laundry basket to collect items that don't belong. Then you can make one quick trip at the end of your time to put those items in their proper place. You can also take a small garbage bag to collect trash. Most of the trash that I find is paper so I just throw that in the laundry basket and take it to the recycling bin.
