Agree wholeheartedly but I worry some will read this and go all in the opposite. The key point is that humility helps make you free. Couple that with not being a slave to frugality and you can live without as much guilt and without a much restraint.

I was so frugal that I didn't refinance my (admittedly already low) interest rate during Covid because "we were planning on selling the house in a year or so". Oh well :)

Most people in the US are pulled into living on credit straight out of school. You get a student loan, then a car loan, then a credit card, then a mortgage. You finance vacations, appliances, kitchen remodels, smartphones - mostly to keep up with friends and coworkers who finance their lifestyles too. A lot of people are in non-stop debt from the age of 18 to 55, if not longer. By most estimates, only about 10-20% of US households are debt-free.

Spending and getting into debt are useful tools. But I don't have any friends in tech who need to be told "hey dude, you should be spending more". I have quite a few friends who would be better off spending less.

For years I did this with the thermostat - something I learned from my father who always kept the house under 65F (18C) in Winter. I'm somewhat ashamed to admit it even led to arguments with my spouse early in our marriage when I would enter a room and find the thermostat set to a balmy 70F.

Eventually I just sat down, looked at how much it costs keep the house a few degrees warmer in winter, and realized we could afford to be comfortable. And if I were really hell bent on saving money, there were other lower-priority expenses I could cut back on first. But I don't even think it was even necessarily about the money - it was more that saving energy and toughing it out felt virtuous to me. Which is all fine, but not something that should be imposed on your partner if they don't share the same beliefs (or if they just get cold easier than you).

I think of this kind of thing whenever HN commenters complain about how some TODO app is using 300Mb of memory or has 700 dependencies.

A wife is a useful thing to have in this respect, not because they tend to profligacy, but because this kind of thing is much easier to detect and fix in someone close to you than in yourself. Both my wife and I have lived frugal lives at various times[0] and I feel much happier with the degree of spending we have now.

I'm reminded of the intelligent corvids in Adrian Tchaikovsky's Children of Memory where the sum of the two birds forms a being with intelligence in a way that the individual segments do not. The frugality is a deeply embedded piece of our being and undoing it seems hard, but together we financially operate in a place that leaves us both feeling comfortable.
