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 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.

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.

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.

Emotional intelligence affects every aspect of the way we live, from romantic to professional relationships, from our inner resilience to our social success. It is arguably the single most important skill for surviving the twenty-first century. But what does it really mean? One decade ago, Alain de Botton founded The School of Life, an institute dedicated to understanding and improving our emotional intelligence. Now he presents the gathered wisdom of those ten years in a wide-ranging and innovative compendium of emotional intelligence that forms an introduction to The School of Life.
