I have often thought that life seems to move in ten-year chapters.

The first ten years are our childhood, when so much is formed in us quietly and deeply, long before we understand what is shaping us. The second ten are our teenage years, when we begin reaching for our own identity and trying to work out who we are. Then come our twenties, those early adult years of choosing, building, striving, and becoming. And so life unfolds, decade by decade, each ten years carrying its own particular weight, its own gifts, its own losses, and its own stretching.

But I have also come to believe that the year before each milestone birthday — 29, 39, 49, 59 and so on — can become a year of contemplation.

Not for everyone perhaps, and not always in the same way, but often it seems to be a year that slows us down. A year that asks us to look back and look forward at the same time. A year that quietly gathers up all that has been and places it before us, asking us to pay attention.

I feel that I am living one of those years now.

And I have felt its weight.

It has asked much more of me than simply noticing my age. It has asked for self-reflection. It has asked me to look honestly at the road behind me and thoughtfully at the road still ahead. It has made me consider not only what I have done, but who I have become. What has shaped me. What has wearied me. What has strengthened me. What still matters most.

At the same time, I find myself standing very consciously between generations.

I am watching the generation before me struggle with the realities of ageing, with frailty, limitation, and the many humbling challenges that old age can bring. There is something sobering about that. Something tender too. It makes life feel both more precious and more fragile.

And then there is the generation after me, living out the busy, demanding, beautiful work of adult life. Building careers, finding their place in the world, buying homes of their own, marrying, raising babies, nurturing children, guiding teenagers, or for some, creating rich and meaningful lives that do not include children at all. Different paths, different callings, different kinds of fullness — and each one carries its own responsibilities, hopes, and questions.

To stand in the middle of all this is no small thing.

It invites contemplation, whether one chooses it or not. You cannot help but notice time. You cannot help but see how quickly life moves, how every generation carries its own burdens, and how no season comes without both beauty and cost.

Perhaps that is why these threshold years feel so significant. They are not only about approaching a new number. They are about being invited into deeper awareness. They slow us down long enough to ask the questions that everyday life can so easily keep pushed aside. What have these years taught me? What have they taken from me? What have they given me? What do I want to carry forward? What is mine to release? And how do I want to enter the next chapter of my life?

The milestone birthday may be the outward marker, but I think the real inner work often begins in the year before. In the quiet year of contemplation. The year that does not let us pass by untouched. The year that asks us to notice, to reflect, to grieve perhaps, to give thanks, and to gather ourselves for what comes next.

And perhaps that is one of the deeper gifts of ageing. Not simply that the years pass, but that if we let them, they can teach us to see more clearly. Ourselves. Others. Time. Life. What matters. What lasts.

At this point in life, standing between those who went before me and those who are coming after, I feel that more than ever.
