Not home declutter, but the volunteer gig. Long story short, we have consolidated 6 locations of stuff combined between the two groups, my group in existence for 35 years. This was our third pass through the accumulated pile. First pass we threw out the obvious-damaged gear, outdated paperwork, and started consolidation of like stuff into totes and placing on shelving. Second pass continued the sorting and consolidation, although one of the crew was questioning everything we were tossing. Years of hoarding stuff "just in case we need it" really slowed us down. At our first meeting after that, I was called a "machine" for my mechanical deliberate approach for evaluation to discard.
Yesterday two of us attacked the collective pile again. Threw out the "keep just in case" stuff after closer examination-stuff that was usable, but damaged. Lots of old totes, thin walled, cracked, crumpled, etc (Still usable!!!) gone. Replaced with heavy duty totes all of the same type for easy stacking.
Actually got things down to a manageable level where we can actually inventory the important stuff.
The new second in command has OCD bad. He said yesterday as we were leaving, he felt much better about the status. We have tossed almost 2 8x8 dumpsters full of stuff so far.
8 trash bags 
It's going to take a couple trips to get this all cleared away!
