+1 to whoever mentioned Seneca's On the Shortness of Life, or any of the Stoic writings. The Old Man and the Sea. People either love or hate this book, but it had a profound impact on me. The Moral Animal, by Robert Wright. Made me consider how much of human behavior can be explained through evolutionary biology. The Truth, by Neil Strauss. Incredibly vulnerable memoir that will make you reflect on your own relationships and what you want out of them. In general, I think that you can learn much more from classic fiction than any new business book. Books that have been read & discussed for the past 50+ years have much more staying power and timelessness than a TED talk that led to a publishing deal.
