The decade that decides

We usually point to the fifties as the decisive moment. That is when we see, which is not the same thing.

The decade that decides lies much earlier: between thirty and forty. And it decides precisely because nothing shows.

Why this decade

Three reasons overlap, and it is their overlap that does everything.

Compensation weakens without disappearing. At twenty-five, a face absorbs everything and teaches no one anything. At forty-five, it no longer compensates and the information arrives too late. Between the two, it begins to respond — faintly, but truly. This is the only window where feedback exists and the time ahead is still long.

Habits become fixed. Most of the routines kept at fifty were adopted in this decade. What takes root there takes root for a long time, for better or worse.

The load of life reaches its peak. This is often the densest period — work, children, parents, building. The pressure on one’s nature is at its highest at the exact moment when available attention is at its lowest.

What is really at stake

Not a state: a direction.

At thirty, two people heading in opposite directions still look alike. At forty, the gap is perceptible and attributed to tiredness or to life. At fifty, it is structural.

Nothing spectacular happened. The distance was travelled.

The classic mistake of this decade

It consists in taking the signs that appear for isolated problems.

A first line, a complexion losing its clarity, skin that no longer reacts as it once did: each of these signs receives a local answer, a product, a correction. And each local answer is reasonable.

What we do not do is read the whole. We correct the successive displays of a system that itself has never been examined. Over ten years, this produces a long, contradictory routine, and a face that is less well than it should be.

What would have the most effect

A single decision, made once, and kept: to know the direction and stop going against it.

It is little work and much effect, for an arithmetical reason. Over ten years, removing what goes against your nature produces more than anything one can add — because contrary actions are not merely neutral, they cancel out the good ones.

And if the decade has passed

The reasoning does not change; only the remaining distance changes.

A change of direction at forty-five acts on the twenty-five years that follow, which is not nothing. It does not recover what has been spent, and there is no reason to pretend otherwise.

What remains true at any age: the most profitable variable is never what we add. It is the direction in which we are going — and it is read from the beginning, not in this year’s mirror.
