You should care, to some extent, about things that happened. You should care a lot less about things people said. And you should care almost not at all about things people said about things people said.
What are you mad about right now? Is it that someone said something about something that someone else said about the opinion of a third person? And is that opinion not even on a thing that happened, but on something said by yet another person?
Too many “saids.” Keep yourself away from that. Just do, and be done.
