Good communication is not about getting your ideas out or *your head*, it’s about getting them into *someone else’s*. You need to understand your audience, their biases, previous learning, and where they stand now. You need to present your ideas in a way that *they* understand, not necessarily in the way that makes most sense to you.
This may or may not be in reference to a math prof I just heard on the radio. He was complaining about what his students didn’t know, in a way that was opaque to most of the listeners to the show. 🙄
