Book excerpt: Learn how to better navigate the challenges of adult life with Gail Sheehy’s landmark bestseller—named one of the ten most influential books of our times by the Library of Congress. For decades, Gail Sheehy’s Passages has been inspiring readers to see the predictable crises of adult life as opportunities for growth. She charts the stages between 18 and 50 as unfolding in a pattern of adult development: once recognized, more easily managed. Passages is an insightful road map of adulthood that illustrates with vivid stories our continuing personality and sexual changes throughout the “Trying 20s,” “Catch 30s,” “Forlorn 40s,” and “Refreshed (or Resigned) 50s.” One comment is continuously repeated by men, women, singles, couples, and people who recover from a midlife crisis: “This book changed my life.”
