> a lingering question of whether any of it truly matters, especially knowing I could stop tomorrow without significantly impacting my wellbeing.
A suggestion for your consideration, or that of anyone in a similar position: give enough of the money away that this stops being true, and find fulfilling paid work (not necessarily in that order). I strongly suspect, from my own experience, that there's an amount of savings that you can keep that is adequate to remove any worry about winding up on the streets (or being stuck with work that actually turns out to suck, etc), without making further earning feel pointless to your own comfort. I think there's an ethical case for doing this even if it made you less happy, but even better if it's win-win.
