The Good Life

The Harvard Study of Adult Development has tracked the same people for more than 80 years — one of the longest longitudinal studies in social science — and Robert Waldinger and Marc Schulz have written the most accessible account of what it found. The answer is not wealth or professional achievement. It is the strength and warmth of your relationships. The book earns its findings rather than just asserting them, and it blends case histories, research, and practical exercises in a way that makes the science readable. Waldinger's related TED Talk has over 42 million views for a reason. The honest caveats are that the central finding may feel familiar to thoughtful readers, and the self-help sections are lighter than the research narrative. But the evidence base is genuinely exceptional, and the message is worth hearing plainly said. Worth It.
