The author is not a domain expert. It's yet another self-help/non-fiction bestseller written from the outside of the relevant field, by a public figure writer, with sprinkles of citations to actual research but still strongly biased towards the authors own worldview. No wonder the subtitle goes for the predictable "subtle art" cliché, as if that could justify handwaving serious frameworks into arbitrary analogies.

If the reader knows nothing of any of the topics, it's all very reasonable and the book can be enjoyed as a good talk with an elder. Unsurprisingly it's also yet another NYTimes bestselling Conservative author preaching his enlightened worldview, so reading between the lines you can see the stereotypical "rational man" coming down with the stoic teachings, but most of the book is pretty benign - even if not super insightful. Alas the book was about to end and the author was able to fit his analysis on Appalachian economics and politics based on ancestry and whatnot.
