The crisis of connection is the crisis of our time.

The longest study of human happiness has one clearest finding.
Started in 1938. Still running. Two cohorts followed for over eighty years, from age 19 into their 90s — physicals every five years, interviews every two, sometimes filmed conversations with spouses and children. The cleanest predictor of who would be happy, healthy, and alive at 80 was not their cholesterol at 50, their wealth, their fame, or even how much they exercised. It was how satisfied they were in their relationships.
On this page: the five-people audit, an attachment-style quiz, the Gottman four horsemen (and their antidotes), the five love languages, the two-minute-call daily commitment with streak, a conflict-style diagnostic, the UCLA loneliness scale, a vulnerability practice, the gratitude-letter exercise (largest single happiness-boost intervention in the literature), and the magic 5-to-1 ratio tracker. Eight decades of research, made small enough to use today.
Chapter 1 · The five people audit (Jim Rohn)
"You are the average of the five people you spend the most time with."
Not literal — but reliably true. Name your five. Rate each on the three numbers that matter: do they fuel you or drain you, do you trust them with the hard things, and when did you last actually be present with them. The asymmetry is the lesson.
Chapter 3 · Gottman's four horsemen of relationship death
Four behaviours predict divorce with 94% accuracy.
From four decades watching couples in his "love lab", John Gottman identified four communication patterns that, when chronic, are catastrophic. Contempt is the strongest single divorce predictor in the literature. Tick the ones that show up in your closest relationship — be honest, this is for you only. Each gets a specific antidote.

Chapter 4 · The five love languages (Gary Chapman)
The shape love takes for you, specifically.
Chapman's framework is not perfect — the original research is thin and the categories overlap — but as a vocabulary for "what makes me feel cared for", it is unbeaten. Pick your primary, then your secondary. Then guess the primary for two people close to you. Notice the gaps.
Chapter 5 · The two-minute call (Robert Waldinger)
"Pick up the phone today. Call someone you have not talked to in too long."
Waldinger's specific prescription. Two minutes. No agenda. Just hearing their voice. Easier than meeting, lower-friction than a "let's catch up properly" you both know will not happen. Done daily, this is the single highest-leverage practice on this entire page.

Chapter 6 · Conflict style (Thomas-Kilmann)
Five ways to handle disagreement. You default to one.
Most people use one style by default, regardless of context. Pick the statements that match how you typically behave when you and someone close to you disagree. Ten questions. The highest score reveals your default.

Chapter 7 · UCLA loneliness scale (6-item)
"Equivalent to smoking fifteen cigarettes a day." — Surgeon General, 2023
Loneliness is the modern epidemic the medical literature now names with the bluntest possible numbers. Vivek Murthy's 2023 advisory: chronic loneliness raises mortality risk equivalent to smoking 15 cigarettes a day; raises cardiovascular risk 29%, dementia 50%, stroke 32%. The scale below is the short-form UCLA. For each, pick how often it is true.

Chapter 8 · Vulnerability practice (Brene Brown)
"Shame cannot survive being spoken." — Brene Brown
Pick one person close to you. Write down one thing you have not yet told them that you would like them to know. You are not committing to send this. The act of writing it is the practice. Choose between a small thing (something you have appreciated and never said) or a bigger one (something you carry and haven't shared). The smaller is often where to start.
Chapter 9 · The gratitude letter (Martin Seligman)
The largest single happiness-boost intervention in the positive-psychology literature.
Pick someone living who has shaped your life in a way you have never properly thanked them for. Write 300 words. Be specific — what they did, how it affected you, what it has meant since. The act of writing produces a happiness boost larger than most antidepressants in their first month, lasting up to three months. You can deliver the letter. You can keep it. The writing is most of the effect.
Chapter 10 · The magic 5-to-1 ratio (Gottman)
Five positives to every negative. In conflict.
Watching couples in conflict, Gottman found stable, happy long-term partnerships maintain at least 5:1 positive-to-negative interactions even when they are arguing. Couples headed for divorce show ratios closer to 1:1 or worse. Log a week of small interactions with one key person. The ratio surprises almost everyone.
Chapter 11 · Voices of connection
Waldinger. Gottman. Perel. Brown. Sue Johnson. Aristotle. And the Harvard study participants themselves.
Each refresh draws another line. Some from the researchers, some from the 95-year-olds they interviewed. Save the ones that find you.
