Sense

the best thing money can buy for me is complete sovereignty over what i do with my time. 

the math for that assumes my current cost of living and adds some non-negotiables (having kids, etc.) but it's more like a percentage increase than a multiple.

so any recurring costs i add or increase makes that more expensive AND gives me less money to buy it, so i have little interest in adding/increasing for now.

a bitcoin mindset helps encourage this as it has been historically true that "if you just wait 4 years" to buy whatever it is you want, you can do so with a portion of your bitcoin and still have more bitcoin remaining in USD terms than you did to start.

all of this however must be balanced with an understanding that life should not be taken for granted and you might work hard and save money to give yourself financial freedom for a lifetime which is not guaranteed. "live like there's not tomorrow" basically is the counterweight.

most assume you must sell most of your time forever, so they just buy things
