Your first task in delivering a persuasive presentation is to establish your credibility and show the audience that they can trust you. The Greeks called it “ethos” — it has to do with your character and your degree of fit with the audience. The audience will ask several questions of you. Does she respect us? Does she use our time wisely? Does she know what she’s talking about? Is she an egghead or does she have the practical wisdom to recommend a practical course of action? Does she share our values? These are all subliminal questions but your actions during the first five minutes of a speaking presentation will answer most of them. Find out more in the video.
