Basically, the title. I'm fluent in my native language (i'm kind of an unbalanced bilingual in the sense i'm worse at my native language than foreign languages), but whenever I try to explain something to another person (like where something is, a situation that happened), I've been told that I make no sense. I jump around and assume way too much knowledge, and when I try to elaborate, I somehow make it worse? I'm not even sure it's an eloquence problem, but does anyone know a way to consciously improve this skill?
