Own less? Minimalism?

The more you own, the more you have to lose. I have so many guitars some, I rarely even use. After a few years, the mechanical parts don’t work as much and I end up spending more to fix it. This can be applied to various other aspects, too many clothes, rooms, homes etc! You have to maintain these and it soon becomes a clutter. I’ve tried my hand at minimalism, not in an elaborate way! I just couldn’t! I started by just keeping 2 spoons, 2 forks and 2 plates around! This, in-fact,  removed some clutter in the kitchen sink. I’m sure if I move this concept to other things in my life, it’s going to be rather economical financially and energy wise.
