I think the OP is just overthinking this. The fact is that people derive joy and satisfaction in different ways. Most people on the board are looking to optimize their life joy, that's all. How it's done, and what $ amount is required to do it, is different for everyone.
For me, all things being equal, I just don't derive much joy from fancy cars, eating out at expensive places, buying clothes/jewelry, etc., so I would never bother spending much money on them.
I derive moderate to much joy from travel, BUT there are some significant downsides to travel, so I spend some money there, but anticipate spending less as I age.
I derive a MASSIVE amount of joy from gardening, reading, being alone in beautiful outdoor locations, so I focus spending there. Fortunately for me, gardening and reading are fairly inexpensive. Unfortunately, the situations and locations I would REALLY like to live in, are not cheap, and come with problematic tradeoffs. So that is an area where I optimize as well as is practical, but not nearly to the extent I wish I could.
This just isn't that complicated. Figure out where your pleasure bang-for-buck lies, and try to optimize it as well as you can. It's not likely to be 'perfect' and most here aren't aiming for that.
