Multiple days? A proper hoarder will take multiple months if there's any stuff of value there. If it's just boxes of old milk bottle tops it might be easier. But a proper hoarder will have a box of milk bottle tops right next to a box of expensive tools or something.

I've done the minimal lifestyle and found it tiring too. I got myself into a state where I wouldn't have any nice things because I would always be thinking it's one more thing to move when I inevitably do. But I don't want to move. I like being in one place and having a home. Hoarding is not the way, but it's ok to have this too.
