I'm deep diving into minimalism after coming back home, I was already a minimalist by nature, but now it's more serious.
My rule is this: if I don't touch it in 1-2 weeks, it must go (unless it's something that has value and I won't be able to buy again, like instruments).
It's incredible how much money we can make by just getting rid of things.
I mostly throw/donate things but later, I need to sell some items. Maybe my things will worth something :) great tips!
