This is a book about how more choices can make you unhappier with the choice you finally make, and how people are inherently bad at making decisions. It was very interesting and gave me some insight into my own thought processes and their emotional result. I was particularly struck by the discussion about careers; as a middle-class Westerner I can do pretty much anything I want to (provided I don't mind incurring a lot of debt) and that leaves me pretty much paralysed. What if I pick wrong? Aaah!
I would recommend this book to just about everyone, particularly people who feel depressed or dissatisfied with their life. Not only does it include a lot of information about how decision-making happens, and how it can screw you up, the best thing about the book is that the last chapter gives some concrete suggestions for how to deal with all the choices available to us.
(Oh, but it has one of the ugliest covers I've seen in a long time.)
