Everyone says they want to be happy. But that's much more easily said than done. What does being happy actually mean? And how do you even know when you feel it? In Happy, Derren Brown explores changing concepts of happiness - from the surprisingly modern wisdom of the Stoics and Epicureans in classical times right up until today, when the self-help industry has attempted to claim happiness as its own. He shows how many of self-help's suggested routes to happiness and success - such as positive thinking, self-belief, and setting goals - can be disastrous to follow and, indeed, actually cause anxiety. Happy aims to reclaim happiness and to enable us to appreciate the good things in life, in all their transient glory. By taking control of the stories we tell ourselves, by remembering that 'everything's fine even when it might not feel that way, we can allow ourselves to flourish and live more happily.
