TED演講的秘密：如何讓你的演講一鳴驚人

We all know that humans are wired to listen to stories, and metaphors abound for the narrative structures that work best to engage people. When I think about compelling presentations, I think about taking an audience on a journey. A successful talk is a little miracle—people see the world differently afterward.

If you frame the talk as a journey, the biggest decisions are figuring out where to start and where to end. To find the right place to start, consider what people in the audience already know about your subject—and how much they care about it. If you assume they have more knowledge or interest than they do, or if you start using jargon or get too technical, you’ll lose them. The most engaging speakers do a superb job of very quickly introducing the topic, explaining why they care so deeply about it, and convincing the audience members that they should, too.

The biggest problem I see in first drafts of presentations is that they try to cover too much ground. You can’t summarize an entire career in a single talk. If you try to cram in everything you know, you won’t have time to include key details, and your talk will disappear into abstract language that may make sense if your listeners are familiar with the subject matter but will be completely opaque if they’re new to it. You need specific examples to flesh out your ideas. So limit the scope of your talk to that which can be explained, and brought to life with examples, in the available time. Much of the early feedback we give aims to correct the impulse to sweep too broadly. Instead, go deeper. Give more detail. Don’t tell us about your entire field of study—tell us about your unique contribution.

If a talk fails, it’s almost always because the speaker didn’t frame it correctly, misjudged the audience’s level of interest, or neglected to tell a story. Even if the topic is important, random pontification without narrative is always deeply unsatisfying. There’s no progression, and you don’t feel that you’re learning.
