If you can’t say what “enough” looks like for you, you’ll keep running after someone else’s version of it.

Without your own definition of enough, the number keeps being set by whoever is nearby. There is always a next level, and since the target moves with your position you can pass every point you once aimed for and still feel behind. The absence of a line is what makes the running endless, not any failure on your part.

Write down what enough looks like in concrete terms, with actual figures or conditions. It will feel arbitrary, and it is still far better than no line. Check it once a year, and change it deliberately rather than by drift.
