Are there others here who have made an inventory of everything that they own?
It's something a few minimalists have done -- Abundantly Minimal counted around 1,370 objects between them, for example.
My wife and I did it last year -- we have about 8,000 items (plus items relating to my hobbies).
We're not minimalists by any means (as you might be able to tell from how much stuff we have), but we've picked up minimalist ideas like having a home for every item, the Konmari 'spark joy' test (and 'thanking' an object before getting rid of it) and the insight that waste occurs when you acquire something not when you throw it out.
And I think minimalists, maybe more than anyone else, would get a lot out of doing an inventory:
* We got rid of over 1,000 objects because as we went through them we realised we didn't need them.
* Many more things found homes than had them beforehand. (And while we don't keep the inventory updated, we do look it up when we can't find something and it usually hasn't moved.)
* We buy less stuff and appreciate what we have a bit more.
I'd be fascinated to hear if anyone here has done a similar count -- even if it's just for one type of object like all your books or clothes; or one room of your house.
You could even use my wife and I as a "not particularly minimalist" benchmark. (Images aren't allowed here, but you can find some graphs and counts by object and by room in my post history.)
