Retirement advice often assumes the point is to stay busy — that the calendar needs filling. The research on who ends up happy in retirement points somewhere narrower. Two patterns keep showing up in the surveys and the long studies, and neither is really about the size of the schedule.
A note on what follows. We are writers and editors reading the research, not psychologists, financial planners, or clinicians. The studies here mostly describe patterns across groups, not rules that predict how any single retirement will go. Read this as reflection on that research, not as advice for your own decisions.
A handful of interests, gone deep on
The evidence for the first habit comes largely from Wes Moss, a certified financial planner who surveyed about 2,000 US households of retirees and near-retirees. In his data, the happiest retirees averaged 3.6 “core pursuits” compared with 1.9 among the least happy — a gap of roughly two activities, but still a small number in absolute terms. The pattern seems to be picking a few things and going deeper into them.
Moss puts curiosity at the centre of it. As he puts it, “Curiosity may have killed the cat, but a lack of curiosity kills happiness in retirement.” That is his framing rather than a proven law, but the depth part shows up clearly in the survey. The happy retirees kept trying to improve at the pursuits they already had. Moss says, “Not only do they find new ones, but they also want to get better at the ones they currently have.”
The rest of the survey fits the same shape. The happy group takes slightly more holidays — around 2.4 a year against 1.4 for the less happy — which is real but modest. Their advantage lies more in what they’ve built up over time in a few activities than in the number of activities themselves.
The friendships work used to provide
The second habit is harder to see, because it looks like something that ought to be automatic. The Harvard Study of Adult Development has been running since 1938, and it keeps landing on the same finding: relationships are the strongest predictor of a happy later life.
Its current director, the psychiatrist Robert Waldinger, has been direct about where retirement tends to go wrong. He says, “Our study has shown that as people transition into retirement, the number one challenge they face is the difficulty of maintaining and/or replacing the connections they made through work.”
Work-friendships are harder to hold on to after retirement than people expect, because most of them were structural — the job kept putting you in the same rooms as your colleagues. Once that stops, the friendships need a new reason to keep going, or new ones have to be built to take their place. Waldinger frames this bluntly: “The people in our 75-year study who were the happiest in retirement were the people who had actively worked to replace workmates with new playmates.” That is one long study’s observation and not a rule for everyone. Still, it fits with Moss’s data, where the happiest retirees reported 3.6 close confidants against 2.6 for the least happy.
What the two habits have in common
Both habits are the kind of thing that has to be chosen rather than drifted into. A core pursuit takes practice to get anywhere with, which is why Moss’s happy retirees keep working on the ones they already have. A close friendship in retirement takes contact you’re now the one arranging, because the office isn’t doing it for you any more.
Both findings come from patterns across many people rather than rules that predict any single retirement. But the retirees who do well in the research tend to have built these two things.
If leaving work has left you feeling unmoored or isolated, that is common and worth taking seriously, and a qualified counsellor or therapist is a good person to talk it through with.
