I used to have a lot of stuff and eventually started “minimalisn” which let to selling most of it. It’s a simple rule for me, if I haven’t used something in the past 1-2 months I’ll think about selling it or giving it away. I only have things I use frequently, and I try to find things that are dynamic enough to be used for multiple different functions so I don’t get more junk. Things are too specialized now a days….
