David Epstein discovered that in most fields - especially those that are complex and unpredictable - generalists, not specialists, are primed to excel. Generalists often find their path late, and they juggle many interests rather than focusing on one. They're also more creative, more agile, and able to make connections their more specialized peers can't see. Provocative, rigorous, and engrossing, this book makes a compelling case for actively cultivating inefficiency. People who think broadly and embrace diverse experiences and perspectives will increasingly thrive.
