Enough Is a Number. Write It Down.

Ask someone how much money would be enough and watch what happens. Almost nobody has an answer. They have a direction — more — and a vague sense that the current amount is not it. Press further and you usually get a comparison rather than a figure: enough to stop worrying, enough to be comfortable, enough that I would not have to think about it.

This is a strange way to run the largest optimisation problem in an adult life. A goal with no defined finish is not a goal; it is a treadmill with a number on the display. And it produces a specific and very common outcome — income rises substantially over a decade, and the sense of insufficiency does not move at all.

Without a defined finish, every raise resets the baseline. You do not arrive anywhere. You just get a better view of the next thing you cannot afford.

Why the number is missing

Partly because naming it feels risky. A specific figure can be wrong, can be judged, can turn out to be unreachable — and vagueness protects you from all three. Partly because the question is genuinely hard: it requires knowing what you want your life to contain, which is a much larger question wearing a spreadsheet costume.

But mostly it is missing because the surrounding culture is organised to prevent it. Almost nothing you encounter in a day is designed to help you conclude that you have enough. The absence of a defined stopping point is not an oversight in the system; it is roughly the whole business model.

Working it out

The exercise is arithmetic, and it takes an evening. It is not investment advice and it will not tell you what to buy — it tells you what you are aiming at, which is the part most people skip.

Start from the life, not the figure. What does an ordinary good week actually contain for you? Where do you live, what do you eat, what do you do on a Saturday, how often do you see the people in the previous article? Cost that week honestly. Most people find their genuinely good week is markedly cheaper than their current one, because a meaningful share of current spending is not producing any life at all — it is subscription drift, convenience under time pressure, and things bought to solve a feeling.

Add the ceiling, not just the floor. Enough is a range with a top. The top is the point past which more money stops buying anything you actually want and starts buying obligations: the larger place that needs maintaining, the better car you are now anxious about. Naming the ceiling is what converts this from a savings target into a decision about how to live.

Then write the number down. Somewhere you will see it again. The act of committing to a figure is most of the value, because it converts an unbounded anxiety into a finite target — and finite targets can be planned for, progressed against, and finished.

What it changes

Mostly it changes what a raise means. With a number, additional income is either progress toward a defined thing or it is surplus, and surplus can be deliberately spent on time, on people, on risk, on generosity. Without a number, additional income is absorbed into the baseline within a few months and produces nothing but a higher floor to defend.

It also makes some large decisions much easier. Whether to take the job that pays more and costs your evenings is nearly unanswerable in the abstract and quite tractable once you know where you are trying to get to, and whether this actually gets you there.

None of this is financial advice, and anything involving debt, tax or investing deserves someone qualified. But the number itself is not a financial question. It is a question about what you want, denominated in currency because currency is what the world happens to keep score in.
