Count how often you finish other people’s sentences. Most of them had a better ending than yours.

Finishing someone’s sentence feels like connection and usually functions as interruption. You are guessing at the ending from your own store of endings, which means you get your idea back instead of theirs. The moment you supply the word, the thought they were building quietly disappears, and neither of you notices what was lost.

Spend a day counting rather than correcting. When you feel the ending arriving, hold it and let the silence run a beat longer than is comfortable. What comes out is often not what you were about to say, and that difference is the whole reason to ask people things.
