I’ve noticed some minimalists go to the extremes of limiting items based on numbers. In a way it’s a bit of a luxury.
Many people keep items or leftover stuff (one time use tools or extra glue, etc) because it saves money and time from having to drive to the store or order it online again incase they need it again. Those just incase items build up but they can end up being handy.
As someone that’s moved every year for like 6 yrs in a row, I sell about 95% stuff I don’t use but I still have a lot of things just in case that take up little space in junk drawer, etc. I think focusing on what you like and enjoy is better. Putting a hard round number on items is too much of a mental waste of time
