My wife's grandma was somewhat of a hoarder too.....her basement had a big room FULL of "deals" from garage sales, the room was jammed with stuff....most of it random and unused. She also had a huge barn/building filled with stuff too.....as well as her bedroom, and a big cabinet in the dining room, and all the kitchen cupboards and drawers....and the garage.....it was horrifying. It took about 6-7 people MONTHS to clean it all out when she died.
All I really horde is car parts, but I keep it pretty well under control just a couple shelves in the garage. And computer junk.....a couple bins in my closet. I try to purge and recycle at least every year or two......at my worst I filled my whole utility trailer with old computer stuff.
I've minimized since then thankfully.
