We spend vast amounts of time acquiring confidence in narrow technical fields: quadratic equations or bioengineering; economics or pole vaulting. But we overlook the primordial need to acquire a more free-ranging variety of confidence - one that can serve us across a range of tasks: speaking to strangers at parties, asking someone to marry us, suggesting a fellow passenger turn down their music, changing the world. This is a guidebook to confidence, why we lack it and how we can acquire more of it in our lives.

In Ancient Greece, when the philosopher Socrates was asked to sum up what all philosophical commandments could be reduced to, he replied: "Know yourself". Self-knowledge matters so much because it is only on the basis of an accurate sense of who we are that we can make reliable decisions - particularly around love and work. This book takes us on a journey into our deepest, most elusive selves and arms us with a set of tools to understand our characters properly.

When trying to deal with our current troubles and anxieties, it can be deeply irritating to be asked to consider our childhoods. They happened so long ago; we can probably barely remember, let alone relate to, the little person we once were. But one of the most powerful explanations for why we may, as adults, be struggling, is that we were denied the opportunity to fully be ourselves in our earliest years. This book is a guide to better understanding our younger selves in order to shape who we wish to be in the future.

We probably went to school for what felt like a very long time. We probably took care with our homework. Along the way we surely learned intriguing things about equations, the erosion of glaciers, the history of the Middle Ages, and the tenses of foreign languages. But why, despite all the lessons we sat through, were we never taught the really important things that dominate and trouble our lives: who to start a relationship with, how to trust people, how to understand one’s psyche, how to move on from sorrow or betrayal, and how to cope with anxiety and shame?

This is a hopeful, consoling, gentle book about failure. Our societies talk a lot about success, but the reality is that no one gets through life without failing–in small and usually also in large ways. Sometimes our failures are very obvious, at other times, we feel we have to conceal them out of shame. This book encourages us to accept the role that failure plays for all of us and to feel compassion for ourselves for the messes we can’t help but make as we go through our lives.
