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.

The modern world can be a complicated, frenzied, and noisy place, filled with too many options, products, ideas and opinions. That explains why what many of us long for is simplicity: a life that can be more pared down, peaceful, and focused on the essentials. But finding simplicity is not always easy; it isn’t just a case of emptying out our closets or trimming back commitments in our diaries. True simplicity requires that we understand the roots of our distractions – and develop a canny respect for the stubborn reasons why things can grow complex and overwhelming.

This is a guide to anxiety: why we feel it, how we experience it when it strikes, and what we can do when we come under its influence. Across a series of essays that look at the subject from a number of angles, the tone is helpful, compassionate, and in the best sense, practical.

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?

Few life skills are as neglected, yet as important, as the ability to remain calm. Our very worst decisions and interactions are almost invariably the result of a loss of calm - and a descent into anxiety and agitation. Surprisingly, but very fortunately, our power to remain calm can be rehearsed and improved. We don’t have to stay where we are now: our responses to everyday challenges can dramatically alter. This is a book that patiently unpacks the causes of our greatest stresses and gives us a succession of arguments with which to defend ourselves against panic and fury.
