To sum up your 20s, in the words of the brilliant scholar Taylor Swift, "we're happy, free, confused, and lonely at the same time." And that's exactly what Meg Jay's The Defining Decade is about — addressing those feelings and setting yourself up for success in the decades that follow. Dr. Jay is never patronizing, despite speaking to a younger audience, and instead offers pointed examples that she does, in fact, understand the obstacles 20-somethings face. For the friend who can't help but be overanalytical, this book will help them wade through the messiness of young adulthood.
