I'm also thinking about whether holding on to stuff that I might need/want again, is about pride.
It makes me feel really good to come up with a use case for an item I've hung on to for the longest time. For me, there might be a bit of vanity involved in hoarding lots of things. So clever to come up with uses!
I might consider how specialist an item is (and #declutter), and keep multi-purpose items. Some kitchen gadgets are the worst in that way. I probably thought it would make me cook more?!
