"My theory is that the things that you own that you’re not using or don’t need aren’t just a waste of money and space: they’re draining you of your energy. Every time you walk past that cookbook that you never opened, or that model airplane kit that you meant to assemble, or the oscilloscope that you haven’t turned on in a year, a little neural pattern fires that says “Someday I should..” or “I always meant to…” or “God, I really ought to take care of that.” Each of these tiny feelings of obligation or regret is almost imperceptible on its own, but their accumulation throughout the day is a burden that you may not even know you’re bearing until it’s gone."
