On Confidence walks us gently and wryly around the key issues that stop us from making more of our potential. We hear about the impostor syndrome, the wisdom of imagining the great in their bathrooms and what Nietzsche and Montaigne (among others) have to tell us about resilience and courage. We often stay stuck with the level of confidence we have because we implicitly regard being confident as a matter of slightly freakish and unrepeatable good luck. In fact, as this essay charmingly shows, the opposite is true.
