My gut reaction is that I just don't see the benefit of extreme minimalism. For me, minimalism is a tool to live a more peaceful life. Extreme minimalism seems more like a challenge or discipline that would create stress. Is this the draw? To test yourself on how little you can do with? Having to be resourceful, ingenuitive and persevere through difficulty?
I'm genuinely asking, I'd love to hear from some folks who derive benefit or satisfaction from this. What draws you? What are you seeking?
I changed from working 40 hours a week to 32 hours per week (4 x 8 hour days) and it has really helped my mental health. Took some adjustment financially, but now I don't even notice! Highly recommend!
