Intuition tells us (as does this book) that all things are not equal when it comes to the way that seemingly random occurences affect individuals. Some people are just luckier than others in terms of how these events appear and play out in their favor. Gunther takes an open-minded approach to the question of luck, and interviews unquestionably lucky and unlucky individuals to see what the common factors are. His analysis includes the expected (lucky people have more opportunities by virtue of their personalities), but he isn't afraid to talk about findings that don't fall nicely into a causal, classical model. Why should a person's state of mind matter in determining their luck, above and beyond how it changes their outward behavior? This book doesn't present the whole answer to that question, but it does lay a good foundation for giving the matter some serious thought.
