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.

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 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 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.

We know that our minds are capable of great things because, every now and then, they come out with a brilliant idea or two. However, our minds are also unpredictable, spending large stretches of time idling or distracting themselves. This is a book about how to optimize these beautiful yet fitful instruments so that they can more regularly and generously produce the sort of insights and ideas we need to fulfill our potential and achieve the contentment we deserve.
