I understand that the advice is coming from (what they consider to be) a good place, but that doesn't change that the advice is coming from a place of ignorance and shows they likely have no understanding of your situation. I've had NTs try this with me, and they get mad when I systematically tell them why their advice is not applicable or coming from a place that shows they have no understanding of my situation. And sometimes they've even told me that I'm just not doing it right, because if I was, it would work.

Generic advice is only good when you can't be bothered to understand someone's situation and feel the need to insert yourself into someone else's life, and without being asked a good amount of the time.
