The quality of our relationships shapes the quality of our lives. PSC 17 – Developing social connections

This isn't a marketing slogan. It's a measured reality. The most robust longitudinal studies, like the Harvard Study of Adult Development, all reach the same conclusion: what predicts our level of happiness, our longevity, our ability to cope with adversity, is the quality and stability of our human relationships.

And yet, in a world where we "like", where we "react", where we "network", our bonds become more numerous but less deep. We connect. But we no longer truly bond.

PSC 17 is the ability to create, nurture and sustain meaningful and healthy relationships over time. It doesn't depend on the intensity, the frequency, or the eloquence of our exchanges. It depends on sincerity, emotional availability, reciprocity.

This competency is worked on from childhood… but can be relearned at any age.

Why is it so important? Because we are fundamentally social beings. Because secure attachment isn't limited to childhood. Because chronic loneliness is today a health risk factor as high as smoking or obesity.

And because even the most brilliant leaders don't last without connection.

PSC 17 isn't the ability to cooperate (PSC 18). It isn't about reaching shared goals, or collective organisation. It's about relationship for its own sake, heartfelt connection, real presence to another.

It's this competency that makes a colleague become an ally. A client become a partner. A stranger become a source of support.

In business? It changes everything. It humanises relationships. It improves trust. It reduces avoidable conflicts. And it supports leaders in the most difficult moments.

A leader without strong social connection quickly becomes an isolated leader. And isolation, among leaders, often precedes burnout or misaligned decisions.

And in your personal life? It's the foundation. No need to have 50 friends. But at least 1 person who listens to you without judging, who understands you even without you speaking. And that takes nurturing.
