The Defining Decade Summary & Overview

Drawing on a wealth of personal stories and fascinating facts, The Defining Decade (2012) argues that, contrary to popular belief, 30 is not the new 20. Author Meg Jay uses her vast experience as a professional psychologist to advise twentysomethings on such issues as choosing a partner, starting a family, picking a career, and generally making the most of one’s 20s. Jay also argues that the years between 20 and 30 are the time to establish serious goals and, because the adult brain is at its most pliable then, to begin to take steps toward reaching them.
