Here’s the plan to declutter your home over a period of a several weeks:

One room at a time.
A different room each weekend.
One corner to the other.
Touch each item one time.
When was the last time you used it?
If you had to buy it again today, how much would it be? Is that worth it to you? If not GIVE IT AWAY!

Items end up in one of three categories:
Donate to charity
Post on Craigs List

If you REALLY have a lot to get rid of, consider renting a dumpster with a neighbor. You can share the cost. Perhaps 3-4 families? Why not?
THEN have a BBQ on the haul away day to celebrate!
