Uncertainty Box

When you are sorting through a room, attempting to declutter, an idea beyond the TRASH, DONATE, KEEP piles is to have a "box of uncertainty."  So as to avoid hold ups in your decision making, if there is an item you're not sure you want anymore but can't quite donate it, put it in the uncertainty box.  That way, you can keep sorting without having to stop and think very long.  A suggestion made by "Miss Minimalist" was to then seal up the filled box, date it, and put it somewhere like the garage or attic for 6 months.  In 6 months, if you haven't needed anything in that box, donate it.
