There are a number of threads in this section that address some of the issues.

Some things will have immense sentimental value, or even some utility left. The type of thing that you'll want in your coffin with you. 😀

It's best to send out an email with an attached PDF depicting an organized list of things you'd like to find a good and welcoming home. Or, local clubs/libraries/new-to-you shops...? Some things might need consignment, but you'd be better off selling on eBay or Craig's list if you're comfortable with that sort of thing. Some forums have a selling sub-forum or classified section, just like the 'off topic' section.

There are nieces and nephews, grandkids, clubs...that might like some of the things.

Or donate...Habit for Humanity, Red Cross, Thrift Stores.

I don't want stuff, especially the nicer things, to just be put in a dumpster, but that is my instruction for my youngest who is the business brain and my executor. What she can't bear to part with she may have, or give away if she knows someone, but I don't want her spending more than an hour pondering over my inventory. It goes into totes and boxes and will be heaved high up over the rim to crash down below.

I won't be using it any more. It's the same with my body....don't need it, don't want it....burn it, compost it....whatever.

The process of downsizing goes so much better with organizing your thoughts, and then making a reasonably comprehensive inventory. Try to hang on to only a very few 'toys' or niceties, enough that you can fill in only two totes. The home won't have much room, and you may find that even those totes now present a problem for you because you're not really interested. A mistake somewhere along the way in your process.

At some point, you will literally have to walk away from 90% of it. It will become part of your past.
