I understand your point. However the book has some advice that includes the concept of a "good enough job" that pays for your wider interests that can't be monetized equally well. I think the truth is neither black nor white.
I enjoyed the article, thanks for the link. It appears to me that the author writes the book placing value of life fulfilment over traditional career success (where extreme focus pays greater dividends). I'm definitely a scanner and have considered it a negative but the author seems to have a positive and potentially useful view on it, I'll probably take a look at the book.
