The advice you receive should be weighed against the purpose of the work.

Advice arrives with the adviser’s purposes attached. A note about making something safer, faster, cheaper or more impressive can be perfectly good and still pull your work toward a goal you never held. Taking every suggestion produces something with no center, assembled out of other people’s aims. The question is not whether the advice is sound but whether it serves what you are trying to do.

Write down what your work is for and keep it in view while you read comments. Accept what moves it toward that, and set the rest aside politely.
