Think about the last time you felt you truly belonged somewhere.
Not welcomed. Not included. Not tolerated or accommodated or politely accepted into a group. But the deeper thing — the felt sense that the people around you actually knew you. That your presence mattered specifically, not generically. That you could walk through the door and something in the room shifted slightly because you were in it.
For some people that memory is recent. For a great many, it requires reaching back further than feels comfortable. For others it is something they have never experienced.
We have been pondering this for a long time — between us, across decades of working with people on the full landscape of their wellbeing. And what we keep returning to is this: belonging is not a feeling that arrives from the outside. It cannot be manufactured by a loyalty programme or a group chat or a beautifully designed space, though all of those things can help create conditions for it. Belonging is what happens when you are genuinely known — and when you feel safe enough to genuinely know someone else in return.
We have largely forgotten how to do both.
What belonging actually requires
Belonging has conditions. It is not simply proximity — you can be surrounded by people and feel deeply lonely, as most of us have experienced at some point in a crowded room or at a party we wished we had not attended.
The research on what genuine belonging requires is remarkably consistent. It needs scale — not too large, not too anonymous. It needs consistency — the same faces, over time, building the accumulated knowledge of each other that transforms acquaintance into something with actual weight. It needs reciprocity — the sense that you are as known as you are knowing, that the relationship runs in both directions. And it needs, perhaps above all else, the experience of being seen accurately — not the version of yourself you project for professional contexts or social media, but something closer to the truth of who you actually are.
These conditions are almost entirely absent from the way most of us move through our daily lives now. We have hundreds of connections and almost no one who truly knows us. We are visible everywhere and genuinely seen almost nowhere.
The result is a specific and recognisable ache — not dramatic enough to name easily, often mistaken for something else.
Restlessness. Vague dissatisfaction.
The sense that something is missing that you cannot quite locate. We have sat with enough people in enough honest conversations to know that underneath almost everything else, this is frequently what is there.
How we learned to live without it
Belonging was never meant to require effort. For most of human history it was simply the condition of being alive — you were born into a community, you lived inside it, you were known by it from childhood to old age. The idea that you might need to seek belonging, to build it deliberately, to find a place where you genuinely fit — this is an entirely modern phenomenon.
What changed was not human nature. What changed was the scale and pace and structure of the world we built. We moved from villages to cities, from stable communities to fluid networks, from lives lived in one place to lives lived across multiple contexts that never quite intersect. We built careers that demanded constant reinvention. We built social lives around performance rather than presence. We built technology that promised connection and delivered, at best, a shadow of it.
And we got very good at pretending this was fine. At filling the space where belonging used to live with productivity, with busyness, with the comfortable numbness of a screen at the end of the day. We learned to mistake being liked for being known. We learned to call networking community. We learned to accept the simulation so fluently that many of us stopped being able to describe what the real thing felt like.
But the body knows the difference. It always does. It does not know how to lie.
Chronic loneliness — not the dramatic isolation of someone with no one, but the quiet, background loneliness of someone whose life is full and whose belonging is thin — produces measurable physiological effects. Elevated cortisol. Disrupted sleep. A nervous system that cannot fully settle because one of its most fundamental needs is going unmet. The body is not designed to live without genuine community any more than it is designed to live without sleep or movement or nourishment.
Belonging is a biological requirement. And we have been trying to run our lives without it.
What we have seen in fifty years of this work
Between us we have spent over fifty years working closely with people. Building grassroots community. Different people, different contexts, different presenting reasons for being in a room together. But a pattern that appears, reliably, across all of it.
The people who transform most profoundly — who make lasting change rather than temporary adjustment — almost always do it in the context of genuine community. Not always a large one. Not always a formal one. But somewhere they feel they belong. Somewhere they are known well enough that pretending is no longer the easiest option. Somewhere the people around them hold a version of them that they are trying to grow into, rather than the version they have always been.
We have watched people spend years and significant sums on individual therapy, coaching, retreats, programmes — all genuinely valuable — and remain stuck in patterns they could not shift alone. And we have watched those same people, placed in the right community, begin to change in ways that months of individual work had not touched.
This is not a criticism of individual support. It is an observation about what community makes possible that nothing else can replicate. We were meant to belong to one another.
But we are out of practice. And somewhere along the way we absorbed the idea that needing community is a weakness — something to be managed privately rather than named honestly. So we hide it. We present to the world a version of ourselves that needs no one. And we carry the ache of belonging quietly, as though it were something to be ashamed of.
The belonging itself is part of the medicine.
Why scale matters more than most people realise
One of the most consistent findings in community research is that genuine belonging cannot survive beyond a certain size. The number most frequently cited — across studies of villages, military units, and sports teams that have maintained cohesion across generations — sits somewhere between 100 and 200 people. Beyond that threshold, anonymity begins to creep in. Faces become familiar rather than known. The quality of attention that belonging requires starts to thin.
Dunbar’s number — the cognitive limit of around 150 stable social relationships that the human brain can meaningfully maintain — is not a social theory. It is a neurological constraint. We are simply not built to genuinely know more people than that.
This is why Sanctuary Penarth will never exceed 180 members. Not as a marketing decision. Not as an exclusivity play. But because we understand, from everything we have studied and everything we have lived, that the belonging we want to make possible cannot exist at greater scale. To grow beyond that number would be to trade the thing that matters most for the thing that looks most impressive.
Being known, not merely recognised. That distinction is everything to us.
What belonging feels like when you find it
It feels, most often, like relief.
Not the dramatic relief of a crisis resolved, but something quieter and more fundamental. The relief of being able to stop performing. Of walking into a space and not having to decide, consciously or unconsciously, which version of yourself is appropriate here. Of being greeted by someone who remembers what you said last time — not because they made a note of it, but because they were actually listening.
It feels like being held without anyone touching you. Like the particular ease that comes from being in a room where you do not need to explain yourself from the beginning. Like the deep, cellular relaxation of a nervous system that has finally registered: I am safe here. These people know me. I belong.
It is medicine.
