The work is finished, but one detail could be improved. The day could hold another task. ‘Could’ opens a possibility without deciding whether it should be used.
For me, the useful question is what the extra effort changes. Does it serve the purpose, correct an important omission or merely extend the activity?
Criteria established in advance
Imagine a task with a clearly agreed goal. Once it is met, the value of another round can be assessed. Continuing then rests on need rather than mere possibility.
Some tasks require precision and thorough checking. Enough cannot therefore be defined by one general instruction. The criteria must fit the consequences and quality requirements of the work.
A clear decision that the work is complete also tells others when they can rely on it.
Remaining energy is a resource
Not all available time and energy need to be spent on one task. They may serve another purpose in relationships, movement, learning or readiness for tomorrow.
I think good quality also includes directing effort towards what matters. Finishing is an active decision when its grounds are clear.
What does finished mean for this particular task, and how can it be recognised? The answer can support both careful work and stopping at the appropriate time.
