This is such an understated take IMO. In our house we are constantly moving things out to reduce clutter, get rid of unneeded items and, maybe most of all, eliminate the stress of just knowing they’re there. Sometimes we get rid of something we later realize we needed. It’s pretty rare, but when it happens it’s almost never anything expensive. How do you put a price tag on your stress level, though? Just get rid of it and spend the $20-50 if you cut a bit too deep. A few “lessons” like that and you’ll be way more in tune with what you actually need. It’s been years since we had to “rebuy” anything at all.
I still think moving again would be daunting, just because we are a family of 6 and there’s no way to move that much furniture easily, much less all the things that fill that furniture. But at least if it happens we don’t have to move a bunch of trash we can’t easily discern the need for.
EDIT: also “getting rid of stuff” doesn’t necessarily mean throwing it away. If you’re willing to give things away there are a lot of people out there who could actually use the things you’re not. Clothes, kitchen gadgets, kids’ toys… especially toys, we have our kids pick several items before every birthday/Christmas to give away to make room for whatever the family is about to give them.
