Revised and reissued for a new generation, The Defining Decade has changed the way millions of twentysomethings think about their twenties -- and themselves.

Our "30-is-the-new-20" culture tells us the 20-something years don't matter. Some say they are a second adolescence. Others call them an emerging adulthood. Dr. Meg Jay, a clinical psychologist, argues that 20-somethings have been caught in a swirl of hype and misinformation, much of which has trivialized what is actually the most defining decade of adulthood.

Drawing from a decade of work with hundreds of 20-something clients and students, The Defining Decade weaves the latest science of the 20-something years with behind-closed-doors stories from 20-somethings themselves. The result is a provocative listen that provides the tools necessary to make the most of your 20s, and shows us how work, relationships, personality, social networks, identity, and even the brain can change more during this decade than at any other time in adulthood - if we use the time wisely.

The Defining Decade is a smart, compassionate and constructive book about the years we cannot afford to miss.
