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... Over two million readersworldwide have engaged with psychiatrist François Lelord's modern fable. Narrated with deceptive simplicity, its perceptive observations on happiness offer us the chance to reflect on the contentment we all look for in our own lives.
