This came recommended by multiple people that I follow. Honestly, it was a "meh" for me. Lots of mini-biographies of "masters" like DaVinci, Darwin, Mozart, Proust, Goethe, Wright Brothers, Einstein, Coltrane, Martha Graham, etc. Lessons dissected from their successes, and categorized. Not a big impact for me. I will read his "48 Laws of Power" at some point but I think Ryan Holiday has perfected this style.
