Can we approach happiness as if it were a science? What is happiness and what is its secret? Is it perhaps a science that you can teach yourself? What are the habits of happy people? Is unhappiness contagious? What role do others play in your happiness? What are the four pillars of happiness? A book that analyzes all the "hows" we have wondered about from time to time, and ultimately answers the big and crucial question: "how can we become happier?" Harvard University professor Arthur C. Brooks and journalist Oprah Winfrey answer the toughest questions in simple terms and invite us to embark on a journey towards happiness, no matter how difficult the conditions we face. This book talks about how happiness works and how we can adopt new habits and behaviors that will help us manage ourselves and focus on the things that matter most to us. Happiness is not elusive. It is a science that we can teach ourselves.
