Enough is a decision rather than a discovery

No amount announces itself as sufficient, so at some point you have to say so.

People often wait to feel that they have enough, as though sufficiency were a sensation that would arrive on its own once the correct threshold was crossed. It generally does not. Whatever the domain, the threshold tends to move as you approach it, because the moment you reach a level it becomes the new floor and the view from there includes another level. Waiting for the feeling is therefore a strategy with no natural end point, and people who use it can spend a very long time in pursuit of a signal that was never going to be sent.

The alternative is to treat enough as something you set rather than something you detect. This means naming, in advance and in concrete terms, what would constitute a satisfactory outcome, and then treating that as binding when you get there. It feels arbitrary because it is arbitrary, in the sense that the line could have been drawn elsewhere. But every line could have been drawn elsewhere, including the invisible ones you are currently operating under without having chosen them. An arbitrary line you selected is at least yours.

This is not a recommendation to stop wanting things, and it should not be read as one. A person can decide they have enough of one thing while remaining hungry about another, which is in fact how most contented and productive people appear to operate. The decision is domain specific and revisable. What it buys you is the capacity to actually register an outcome as good when it happens, rather than converting it immediately into a new baseline and continuing on unchanged, which is the default and costs more than it appears to.
