You’re on the right track, but I think it’s a bit deeper than just needing something to work on or stay busy with. I effectively retired a few years ago and have spent the time since engaging in various “work” across the kinds of categories you mention. Yet, all of these efforts have carried a sense of purposelessness—a lingering question of whether any of it truly matters, especially knowing I could stop tomorrow without significantly impacting my wellbeing.

This contrasts sharply with the purpose I felt when I had less money and was struggling to build my business. Back then, everything felt deeply do-or-die meaningful. Now, no amount of exercise, goodwill, or intellectual pursuits compares in terms of providing that same sense of purpose.

I don’t think humans need the pursuit of money itself to be happy, but once the foundational needs in Maslow’s hierarchy are met, the higher levels often feel less urgent—and, paradoxically, less fulfilling. There seems to be diminishing returns from “work” as a source of purpose.
