There is a simple formula for any talk:Tell them what you are going to tell them.Tell them.Then, tell them what you told them.As you approach the end of your talk, say something like,“Let me briefly restate these main points…”You then list your key points, one by one, and repeat them to the audience, showing how each of them links to the other points.Audiences appreciate a linear repetition of what they have just heard.This makes it clear that you are coming to the end of your talk.
