“Stumbling on Happiness” by Dan Gilbert, a psychologist at Harvard is  a book that I am longing to read.

 Malcolm Gladwell reviews the book: I suppose that I really should go on at this point, and talk in more detail about what Gilbert means by that—and how his argument unfolds. But I feel like that might ruin the experience of reading Stumbling on Happiness. This is a psychological detective story about one of the great mysteries of our lives. If you have even the slightest curiosity about the human condition, you ought to read it. Trust me.
