There is a lot I love about this book. It's well written and it makes its points very well. The focus on the stoics I especially love. It has two faults though. The first is its omission of any focus on practical application of the ideas it puts forward. The second is that while it's clearly written for a US audience and so has lots of references to icons of that culture, which is fine, claims that persistence and other similar traits are uniquely American (sic) limit the credibility of the author as an educated global citizen.
