I have, still am but getting to the end, of knowing what we have and where it is when we need it. Otherwise what's the point?
I have little sentiment, H is much worse, but we have to work with the house we have and the people we have in iit.
i get rid of books I will never read again, as there's always new stuff to read, clothes, additional tools, paperwork, rags, old electronics, toys outgrown, coats no one wears, kitchenware. It takes time to keep stuff, to store, mend, clean around and that's my motivation to have as much time to live not look for things or move things around.
I needed some turquoise and burgundy cotton for a bit of hand sewing yesterday, found them in 2 minutes, sewing took 20 minutes. In the past it might have taken 20 minutes just to find the sewing box so would have kept putting it off. I fixed two drawers in our chest of drawers this week in an hour because I know where stuff is. Put up an extra hook on back of shower room door in the time it took for the kettle to boil. Things get done if it takes minimum time to find stuff.
So we have stuff in our house because we like reading, board games, some toys, art, technology, exercise equipment, making different food. It's not minimalist. But it's not hoarding.
