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

Our "thirty-is-the-new-twenty" culture tells us the twentysomething years don't matter. Some say they are an extended adolescence. Others call them an emerging adulthood. In The Defining Decade, Meg Jay argues that twentysomethings have been caught in a swirl of hype and misinformation, much of which has trivialized the most transformative time of our lives.

Drawing from more than two decades of work with thousands of clients and students, Jay weaves the latest science of the twentysomething years with behind-closed-doors stories from twentysomethings themselves. The result is a provocative read that provides the tools necessary to take the most of your twenties, and shows us how work, relationships, personality, identity and even the brain can change more during this decade than at any other time in adulthood--if we use the time well.
