You make hundreds of decisions every day, from what to eat for breakfast to how to influence people, and not one of them could be made without the essential component of emotion. It has long been held that thinking and feeling are separate and opposing forces in our behaviour. But as best-selling author Leonard Mlodinow tells us, extraordinary advances in psychology and neuroscience have proven that emotions are as critical to our well being as thinking.

How can you connect better with others? How can you improve your relationship to frustration, fear, and anxiety? What can you do to live a happier life? The answers lie in understanding emotions. Taking us on a journey from the labs of pioneering scientists to real-world scenarios that have flirted with disaster, Mlodinow shows us how our emotions help, why they sometimes hurt, and what we can make of the difference.

Cutting-edge research and deep insights into our evolution, biology, and neuroscience promise to help us understand our emotions better and maximize their benefits. Told with characteristic clarity and fascinating stories, Mlodinow’s exploration of the new science of feelings is an essential guide to making the most of one of nature’s greatest gifts to us.
