If you are going to read one book this year, I’d recommend Sapiens, by Yuval Noah Harari. I think it would make for a great vacation read, if you don’t mind non-fiction on the beach.
The book reminded me of another old favorite of mine, Jared Diamond’s Guns, Germs & Steel. However, I found Sapiens to be more philosophical and funnier. It also coincided with a period for me where I am trying to connect many dots at work, and provided good accompaniment to my mental process.
