You don't have to be making money for your time to be worth something. I'm home from work right now. If an hour spent clipping coupons takes away from "recreational" time spent coding for fun or in my machine shop puttering around, it's not worth it. The leisure time is worth more to me than the money the coupons would save.
again, i feel this is a false dichotomy. it doesn't always come down to making the choice of spending an hour clipping coupons or doing something you enjoy.
sometimes you have idle time and have the choice between spending 10 minutes to clip some coupons while watching tv, or doing nothing.
