Precision is respect for the difference details can make.

Being precise is usually framed as fussiness, but it is closer to a form of respect. It says that the difference between roughly and exactly could matter to whoever depends on this, and that you would rather carry the small cost of care than pass on an unknown risk. Details are where the effect of your work actually happens.

Before you release something, ask who will rely on it and what part of it they cannot check for themselves. That is where the precision belongs. It is not about being flawless everywhere, it is about being careful specifically where your carelessness would become someone else’s problem.
