A room decides how carefully to listen to you in roughly the first ninety seconds, and that decision is difficult to undo later in the talk. Which makes the opening worth more preparation than its length would suggest.
A strong opening does three things, in order: it states plainly what this is about, it gives the room a reason this matters to them specifically, and it tells them, directly or implicitly, what they’ll be able to do or decide by the end. What it doesn’t need is a joke, an apology for being nervous, or a slow build-up. All three spend seconds you don’t have on establishing something other than your point.
Do this now. Take a talk you actually have coming up (real, or if none is scheduled, one you gave recently) and write its opening in exactly three sentences: what this is about, why it matters to this specific room, and what they’ll walk away with. Read it aloud and time it. If it runs over ninety seconds, the most common cause is trying to include too much context before getting to the point. Cut context, not substance.
Keep this opening. Lesson seven builds the structure that the rest of the talk hangs off, and it starts exactly where this ninety seconds ends.
