You cannot put the same shoe on every foot.

A method that fits one situation will pinch in another, and the fit matters more than the quality of the method. Advice that transformed somebody’s life often fails for you not because it was wrong but because you are not them. The same holds for the rules you hand other people.

Where you are applying a single standard across different people or projects, check whether it is actually serving each of them. Ask what this particular case needs rather than what usually works. Being consistent is worth something, though not more than being useful.
