>Could you explain what you mean?Sure.
I realize I waste a lot of time in supermarkets, shops or online stores, browsing/walking around and comparing prices just to penny pinch on low value things, when the savings I would make would have no meaningful impact on my yearly net worth, but the time and mental energy wasted browsing/walking around comparing prices could have better return on investment if used on other things like learning a new skill, reading a book, etc.
I avoid any kind of subscription services (Netflix, Spotify, cloud-storage, phone contract, etc.) to the disbelief of my friends ("But it's only 10 Euros a month!, Why don't you have it?"), preffering instead to spend my time building my own self-hosted solutions for cheap, which probably explains how I got into tech in the first place.
I own a cheap old car and prefer to fix it myself if I can, rather than paying someone to do it, even though the time I spend learning how to fix it, buying the parts, then actually fixing it, is probably worth more than a professional would have cost.
I'm afraid to make investments fearing that the market could crash the second I enter it, and erase my money, leaving me vulnerable to being homeless or dependent on doing shitty jobs I hate just to stay afloat, so I just hoard cash like an idiot as that makes me feels safe and lets me sleep well at night.
I think I might not be good enough for some bold career steps, like giving up my tech job and risking everything to start my own business of a coffee cart in the city center or pivoting to something other than tech that's less well paid, like being a teacher.
I spent too much of my youth studying hard at useless subjects on the pressure from my parents that "education will get you far in life, so beat those books and get good grades", only to realize far too late in life that I could have gotten in the same spot with 20% of the effort, leaving me time to actually enjoy my youth.
Sure, I'm working my way out of these habits slowly, but the Pavlovian impulses are still in my brain. Complex things these minds of ours.
