Sobre o livro
This book will change your life by showing you how life changes. Why does happiness get harder in your 40s, regardless of gender, race, class or nationality? Why do you feel in a slump even when you're successful? Where does this malaise come from? And, most importantly, will it ever end? In this book, drawing on cutting-edge research, the author answers all these questions. He shows that from our 20s into our 40s happiness follows a well documented U-shaped trajectory, a 'happiness curve', declining from the optimism of youth into what's often along, low trough in middle age, before starting to rise again in our 50s.
