Why HN recommends it

Level-headed, systematic take on frugality and financial independence that reframes spending and consumerism rather than offering typical money-advice tips; suits readers who want a philosophy plus practical examples.

This, and in addition, read https://www.amazon.com/Early-Retirement-Extreme-philosophica... You don't need more, trust me. But, of course, what these two have in common, is simply: 1.

From a more practical angle, I wish I had had "Early Retirement Extreme" by Jacob Lund Fisker [2] in my shelf at that age. Don't get fooled by the title, this is by no means a "highway to financial independence" book; rather, it's a really deep book about, well, sensible…
