A great merging of Buddhist calm and capitalist drive, at least on the page — wealth in one half, happiness treated as a skill in the other. I'm a Buddhist in the loose sense, so the second half felt familiar; the first half reminded me of ambitious people in London who burned out chasing outcomes they didn't even want.
What I took from it is the vibe more than any single line: how to succeed without going crazy, keep the ego from running the show, stay calm enough to think. Some aphorisms age badly if you're broke; others I still flip back to when work is noisy.
Not gospel for me — more like a useful counterweight on the shelf.
