TED演講的秘密：如何讓你的演講一鳴驚人

With so much technology at our disposal, it may feel almost mandatory to use, at a minimum, presentation slides. By now most people have heard the advice about PowerPoint: Keep it simple; don’t use a slide deck as a substitute for notes (by, say, listing the bullet points you’ll discuss—those are best put on note cards); and don’t repeat out loud words that are on the slide. Not only is reciting slides a variation of the teleprompter problem—“Oh, no, she’s reading to us, too!”—but information is interesting only once, and hearing and seeing the same words feels repetitive. That advice may seem universal by now, but go into any company and you’ll see presenters violating it every day. Many of the best TED speakers don’t use slides at all, and many talks don’t require them. If you have photographs or illustrations that make the topic come alive, then yes, show them. If not, consider doing without, at least for some parts of the presentation.

Video has obvious uses for many speakers.?Used well, video can be very effective, but there are common mistakes that should be avoided. A clip needs to be short—if it’s more than 60 seconds, you risk losing people. Don’t use videos—particularly corporate ones—that sound self-promotional or like infomercials; people are conditioned to tune those out. Anything with a soundtrack can be dangerously off-putting. And whatever you do, don’t show a clip of yourself being interviewed on, say, CNN. I’ve seen speakers do this, and it’s a really bad idea—no one wants to go along with you on your ego trip. The people in your audience are already listening to you live; why would they want to simultaneously watch your talking-head clip on a screen?

Ultimately I learned firsthand what our speakers have been discovering for three decades: Presentations rise or fall on the quality of the idea, the narrative, and the passion of the speaker. It’s about substance, not speaking style or multimedia pyrotechnics. It’s fairly easy to “coach out” the problems in a talk, but there’s no way to “coach in” the basic story—the presenter has to have the raw material. If you have something to say, you can build a great talk. But if the central theme isn’t there, you’re better off not speaking. Decline the invitation. Go back to work, and wait until you have a compelling idea that’s really worth sharing.
