Used the 'spend 10 minutes in one room, finding, or at least looking for, disposable clutter' method.
I was in the guest bedroom. I thought I had already gone through the stuff here, but I found some huge plastic tubs I had not apparently opened. Cleaned the dust off first, then pried one open. Eureka! Full of clean used slacks from the girl friend. The size was pretty big so they would be a hard sell at the rummage sale. Also a few big plastic bags of slacks.
All told, I took off three big plastic bags of slacks to the Salvation Army this morning.
I have so many different parts of the house full of clutter, I have to force myself to pick one place, and just 'be there' amidst it all, no escape, just do something, no procrastinating, even if if all you do is identify what's there. I actually look at the clock before starting.
Feeling good about getting rid of the three big bags! Taking a break now, lol.
