What makes a good life by Robert Waldinger

The Premise: The Good Life​

A recent survey of Millennials found that their most important life goals were to get rich (over 80%) and to become famous (50%). However, the Harvard study—the longest study of adult life ever conducted—reveals a very different truth about what truly determines a happy, healthy life.

The Study​

  • Duration: 75 years (started in 1938) and is still ongoing.
  • Participants: Originally 724 men across two groups:
  • Group 1: Sophomores at Harvard College, many of whom went on to serve in WWII.
  • Group 2: Boys from Boston's poorest and most disadvantaged families living in tenements.
  • Tracking: Researchers tracked their lives, work, health, and home life through interviews, medical exams, blood draws, brain scans, and videotaped conversations with their wives.
  • Key Finding: The lessons are not about wealth, fame, or working harder. "Good relationships keep us happier and healthier. Period.".

3 Big Lessons About Relationships​

The study identified three core findings about how relationships affect long-term health and happiness:

1. Social Connections Are Good, Loneliness Kills​

  • Health Benefits: People who are more socially connected to family, friends, and community are happier, physically healthier, and live longer than people who are less connected.
  • The Toxicity of Loneliness: People who are more isolated than they want to be are less happy, their health declines earlier in midlife, their brain functioning declines sooner, and they live shorter lives.
  • Note: You can be lonely in a crowd or even in a marriage.

2. Quality, Not Quantity, Matters​

  • Focus on Closeness: It is the quality of your close relationships that matters, not the number of friends or whether you are in a committed relationship.
  • Conflict is Toxic: Living in the midst of high-conflict marriages (without much affection) is detrimental to health, perhaps even worse than getting divorced.
  • The Predictive Power of Age 50: Researchers looked at data from when the men were age 50 to predict who would be happy and healthy at age 80.
  • It was not their middle-aged cholesterol levels that predicted longevity.
  • It was how satisfied they were in their relationships that predicted health at age 80.
  • Buffer Against Pain: Happily partnered people reported that on days they had more physical pain, their moods stayed just as happy. For those in unhappy relationships, physical pain was magnified by emotional pain.

3. Good Relationships Protect the Brain​

  • Secure Attachment: Being in a securely attached relationship (feeling you can truly count on the other person in times of need) in your 80s is protective.
  • Sharper Memory: People in these secure relationships have their memories stay sharper longer.
  • Bickering vs. Trust: Relationships don't have to be smooth all the time; some couples bicker daily. However, as long as they felt they could count on each other when the going got tough, those arguments did not take a toll on their memory.

Conclusion: A Lifelong Investment​

People seek a "quick fix" for a good life, but relationships are messy, complicated, and a "lifelong" job that never ends.

  • The Happiest Retirees: The people in the study who were happiest in retirement were those who had actively worked to replace their workmates with new friends and "playmates".
  • Final Call to Action: The people who fared the best were those who leaned into relationships with family, friends, and community.

To lean into relationships, Waldinger suggests:

  • Replacing screen time with people time .
  • Livelying up a stale relationship by doing something new together.
  • Reaching out to a family member you haven't spoken to in years, as holding grudges takes a terrible toll

He concludes with a quote from Mark Twain: "The good life is built with good relationships".
