Conventional wisdom would have us believe that it is the size of your network that matters: how many people do you know? We're told to mix, mingle, and connect. But social science research suggests otherwise. The quality and structure of our relationships have far greater impact on our personal and professional lives. Our relationships with friends, family, co-workers, neighbours, and collaborators are by far our greatest asset. Yet, most people leave them to chance. In this ground-breaking study, Marissa King, Professor of Organizational Behavior at the Yale, argues that there are strategic ways in which we can alter our relationships for a happier and more fulfilling life. With new understanding, this book can help readers to see how they can harness the power of their networks in their personal relationships, at work, and to create a better world.
