A great little book from Harvard professor Daniel Gilbert; on the delusion on happiness. Events that we anticipate will give us joy and make us happy, make us less happy than we think. On the other hand things that fill us with dread will make us less unhappy, for less long, than we anticipate. This is New York Times sum up of the book adding that as evidence, Gilbert cites studies showing that a large majority of people who endure major trauma (wars, car accidents, rapes) in their lives will return successfully to their pretrauma emotional state - and that many of them will report that they ended up happier than they were before the trauma. Stumbling on happiness is filled with interesting information like that all relating to the subject of happiness.
