@gosha There is so much satisfaction to be derived from that moment you decide to make do with what you have at hand, and of replacing something only when it has truly disintegrated beyond repair. I think it’s a good experiment!

@gosha The only new things I have bought in the past few years are books (a few each year), art materials (once a year typically, mostly paper and/or fabric) and potted plants. I don't feel like I'm missing anything at all.
Maybe you feel it's not a good way to live for you, but it definitely works for me.
I do spend money on non-essential things though: going for coffee with a friend, taking the train to go hiking.
