I darned $40 worth of socks with this $15 kit this weekend instead of throwing them out, and repaired the pockets on two jackets that would have been $30 each to have repaired at the seamstress. I’d say that’s a $100 DCA justification. Time spent: 3 hours while listening to podcasts. I never would have done it if I had never lowered my time preference and started saving in #bitcoin .
