We are trapped inside our own heads. Our beliefs and understandings about the world are limited by that perspective… Of course, then, we mistake that story we’ve constructed of our lives as the truth.

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?

Across the millennia, philosophers have thought long and hard about happiness. They have defined it in many different ways and come up with myriad strategies for living the good life. Drawing on this vast body of work, 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.

This brilliant, candid and deeply entertaining book exposes the flaws in these ways of thinking, and in return poses challenging but stimulating questions about how we choose to live and the way we think about death.

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 to live more happily.
