Better than a thousand hollow words is one word that brings peace.

Volume of speech and value of speech are not related. Long explanations often serve the speaker: they discharge anxiety, establish position, fill a silence that felt dangerous. A single sentence that settles something for the person hearing it does more work than an hour of talk, and it usually requires you to have understood them first.

Before your next difficult conversation, decide the one thing that would help most if they heard it, and lead with that. Then stop talking earlier than feels natural. The silence you are tempted to fill is often where the useful part of the exchange happens.
