I really like this framing as it's tangible in a way I've considered overall expenses but haven't particularly applied to eating and cooking. I think it also gets at why I'm even concerned about controlling the expense beyond the feeling factor, as I can recognize although my after-tax hourly earnings is several times higher per hour currently than the potential savings, my income from year to year is variable, and so cutting this expense down now in addition to increasing my investments increases the likelihood that in the future I can continue to avoid cooking and cleaning without paying a premium against my time for doing so (eg. 1.2 hr of work to avoid an hour of cooking/cleaning I still might do but would be a much harder calculus for me)
