I stumbled upon this book on Goodreads website as part of give-away competition. And because it has so interesting title, I almost immediately decided to buy its digital edition through Amazon (did also checked book’s site beforehand). After reading it whole I am not regretting buying it. That is because it was fun and I also learn something about real world (for example when Zack is describing to Klatu about stocks). Book also made me think about which virtues are more important to me: happiness or knowledge (as this is also the main theme of the book).
