Tested again and again, by different people, and it keeps coming out the same. You can lean on this.

  • Waldinger & Schulz, The Good Life (2023)

Why it works

It is the longest study of adult life ever run, and its single strongest result is not about money, fame, class or diet. Loneliness is as damaging to mortality as smoking.

What to do about it

  • Treat relationships as maintenance work with a schedule, not as something that happens naturally.
  • Audit: name the eight people who matter most and when you last spoke properly. Fix the worst gap this week.
  • Replace passive contact (liking, watching) with live contact (calling, meeting). Only the live kind counts.

Where people go wrong

Assuming the people who matter know they matter. Almost nobody does.

Where this fits in your day
