The good life is built with good relationships.
About the author
Robert J. Waldinger (born 1951) is a Clinical Professor of Psychiatry at Harvard Medical School and the fourth director of the Harvard Study of Adult Development, the longest-running scientific study of adult life ever conducted.
The study he directs began in 1938 as 2 separate projects. One tracked 19-year-old Harvard students. The other followed a group of juvenile delinquents from Boston. Both groups were exclusively white, male and Boston-based. Over time, their wives were brought in, then their children. The combined group eventually numbered 725 men (among them was John F. Kennedy). For 85 years, researchers photographed, audio- and videotaped participants, drew their blood, scanned their brains and studied their DNA, all in pursuit of one question:
“What does it take to live well?”
Waldinger presented the study’s findings in a 2015 TED Talk, What makes a good life? Lessons from the longest study on happiness, which became one of the most-watched TED Talks of all time. The quote comes directly from that talk and from his 2023 New York Times bestselling book, The Good Life, co-authored with Marc Schulz.
What makes Waldinger’s story worth paying attention to is that the research changed him personally. He had spent years working around the clock, proud of his academic output. Then his own data stopped him. He started calling friends he had let drift, telling them he was thinking of them, inviting them for walks or dinner. He said his greatest source of satisfaction turned out to be not the awards on his wall, but the warmth of his connections with other people.
“I am not revealing something to this world that’s a shocker. We just now have good scientific data to back up what our grandmothers always knew and were telling us all along.”
The combination of scientific rigour and personal humility is what sets Waldinger apart. He isn’t selling a self-help formula. He’s reporting what 85 years of evidence actually shows, and then admitting that his grandmother probably could have told you the same thing.
The meaning of the quote
Most people, when asked what they want from life, say some version of the same few things: more money, a better job, a bigger house, more time. The Harvard Study found that none of those things predicted who ended up healthy, happy and sharp into old age. The people who thrived were the ones with strong, warm connections to others. Not the wealthiest. Not the most decorated. The most connected.
People with strong social bonds were less likely to develop heart disease, diabetes or arthritis. Broader social networks slowed cognitive decline. Married people lived longer, an average of 5 to 12 years longer for women and 7 to 17 years longer for men. Loneliness, by contrast, turned out to be as damaging to the body as smoking.
But the quote isn’t just a health tip. It asks you to look at where you’re actually putting your time and energy, and whether that matches what the evidence says matters.
Waldinger points out that the good life gets defined for us rather than by us. Social media, advertising, and the constant visibility of other people’s curated highlights push us toward measuring ourselves by wealth and status. As one of his mentors put it, we spend our lives comparing our insides to other people’s outsides. The quote cuts through that claiming that relationships are the foundation, not the reward you get after you’ve achieved everything else.
Waldinger is careful to say the answer isn’t the same for everyone. Introverts may need only a handful of close relationships and find large social circles draining. Extroverts need a wider net. About 50% of your baseline happiness comes from temperament, roughly 10% from life circumstances, and about 40% is within your control. That 40% is where the quote lives.
So what does building with good relationships look like in practice? Waldinger offers a few concrete moves.
The study also found that the skill of building and maintaining relationships has been declining in the US since the 1950s. People are half as likely to join clubs or civic organisations as they were 70 years ago. Family dinners and vacations are down by a third. In 1983, 12% of Americans had no one they could speak to about personal matters. By 2003, that number had doubled to 25%. Half of all CEOs report feeling lonely.
The quote, then, is both a finding and a warning. It tells you what works. It also implies that the direction most people are drifting is away from it.
Waldinger describes the good life not as a destination you arrive at, but as a path, and the people walking it with you are the point. The study’s clearest signal, across 85 years and hundreds of lives, is that the warmth of your relationships is what holds everything else up. Build there first.
