Enough is a number, and if you do not set it, the market will set it for you.

Income rises and the lifestyle rises silently alongside it. The new salary feels tight within four months and you cannot point to a single thing that changed. The floor simply rose.

That is not a maths problem, it is a definition problem. Without a written line marking sufficiency, every increase is absorbed before it is ever enjoyed.

Write your number. What does a good, unanxious month actually cost? Then let everything above that line become a deliberate choice rather than a default you never noticed making.
