People today are often bombarded with messages about success and happiness, usually equating them with wealth, fame, and professional achievement. But what if the true secret to a fulfilling life has been misunderstood? A groundbreaking Harvard study over seven decades may answer what makes us happy.

The origins of the happiness study

In 1938, Arlie Bock, the then-head of Harvard’s health services, initiated an ambitious research project. He noticed that while much attention was given to why people fell ill or failed, little was understood about what makes people healthy, successful, and happy. Thus began one of the longest-running studies in human history, aiming to transform the lives of its subjects into a single answer to the question: What kind of person lives the happiest life?

The happiness study participants

The study initially focused on 268 Harvard undergraduates, believed to be the crème de la crème of society with strong self-discipline. These young men were the epitome of success potential: healthy, intelligent, and well-educated. In parallel, the Glueck Study examined 456 young men from Boston’s poorer neighborhoods, providing a contrasting backdrop to the Harvard elite.

Merging paths

Eventually, the Grant Study (Harvard undergraduates) and the Glueck Study (Boston youth) merged, bringing together 724 male participants whose lives would be meticulously recorded and analyzed. This cohort experienced wars, economic downturns, personal triumphs, and tragedies, including the lives of individuals like President John F. Kennedy.

The findings

After seven decades and hundreds of thousands of pages of interviews and medical records, the study revealed profound insights. Robert Waldinger, the study’s fourth director, presented these findings in a TED talk in 2015, debunking common misconceptions about happiness. Wealth, fame, and high achievement were not the key factors; instead, the quality of social relationships was paramount.

The three pillars of happiness

  • Loneliness vs. connection: Those who maintained close relationships with family and friends were happier, healthier, and lived longer than their isolated counterparts.
  • Quality over quantity: It’s not about how many friends you have or whether you’re married. Toxic relationships are more detrimental than being alone. A happy marriage at 80 can mean a sharper, healthier brain.
  • Protective relationships: A supportive relationship can shield our brains. Trust in a partner at an old age is linked to better memory retention.

Additional insights into happiness

  • Economic success: Beyond a certain IQ level, wealth correlates more with relationship quality than intelligence.
  • Childhood love: Warm childhood relationships, especially with mothers, predict higher earnings and better mental health in later life.
  • The challenge of maintaining relationships: Despite the clear benefits, maintaining positive relationships is not always easy. We often get caught up in petty arguments, hold grudges, and focus on negative interactions. Social media can exacerbate this by offering superficial connections at the expense of deeper, more meaningful ones.

Conclusion: Embracing the wisdom of experience

As we navigate the complexities of modern life, it’s easy to lose sight of what’s truly important. The Harvard study serves as a potent reminder that the richness of our lives is deeply rooted in the quality of our relationships. Mark Twain’s words resonate as much today as they did over a century ago: “Life is fleeting, so let’s not waste it on the trivial. Instead, let’s invest our time in love, for even a moment of genuine connection is priceless.”

In a world where many are redefining success, the Harvard study’s message is clear: Invest in your relationships, cherish your connections, and you may find the happiness that has eluded you for so long.
