At the start of 2017 I checked the actuarial tables and determined, at 12 books per year, I had about 168 books left to read. Give or take. That's not a lot. So I decided then and there that I would read only books that had the potential to change my mind, or change my life.
Yuval Harari's Sapiens is one of them, not only because it's as absorbing as a novel, but I now believe it explains nearly everything that has confused me about life and my fellow human beings since November 2016.
