Hector and the Search for Happiness (Film tie-in edition)

Can we learn how to be happy? Hector is a successful young psychiatrist. He's very good at treating patients in real need of his help. But many people he sees have no health problems: they're just deeply dissatisfied with their lives. Hector can't do much for them, and it's beginning to depress him. So when a patient tells him he looks in need of a holiday, Hector decides to set off round the world to find out what makes people everywhere happy (and sad), and whether there is such a thing as the secret of true happiness.
