What makes for a happy life, a fulfilling life? A good life? According to the directors of the Harvard Study of Adult Development, the longest scientific study of happiness ever conducted, the answer to these questions may be closer than you realize. What makes a life fulfilling and meaningful? The simple but surprising answer is: relationships. The stronger our relationships, the more likely we are to live happy, satisfying, and overall healthier lives. In fact, the Harvard Study of Adult Development reveals that the strength of our connections with others can predict the health of both our bodies and our brains as we go through life.

The invaluable insights in this book emerge from the revealing personal stories of hundreds of participants in the Harvard Study as they were followed year after year for their entire adult lives, and this wisdom is bolstered by research findings from this and many other studies. Relationships in all their forms–friendships, romantic partnerships, families, coworkers, tennis partners, book club members, Bible study groups–all contribute to a happier, healthier life. And as The Good Life shows us, it’s never too late to strengthen the relationships you have, and never too late to build new ones.

Dr. Waldinger’s TED Talk about the Harvard Study, What Makes a Good Life, has been viewed more than 42 million times and is one of the ten most-watched TED talks ever. The Good Life has been praised by bestselling authors Jay Shetty ( Robert Waldinger and Marc Schulz lead us on an empowering quest towards our greatest need: meaningful human connection ), Angela Duckworth ( In a crowded field of life advice and even life advice based on scientific research, Schulz and Waldinger stand apart ), and happiness expert Laurie Santos ( Waldinger and Schulz are world experts on the counterintuitive things that make life meaningful ).

With warmth, wisdom, and compelling life stories, The Good Life shows us how we can make our lives happier and more meaningful through our connections to others.
