W: Tonight, we have Chris Anderson, the owner of TED and TED Talks, to talk to us how to give a public talk. Welcome!
M: Thank you. Well, the process of one human speaking to others has deep biological roots. We have evolved these techniques over hundreds of thousands of years, but someone still gets nervous when giving public talks.
W: True. What are your suggestions then?
M: The single most important thing to do, if you have to give an important talk in a limited period of time, is get rid of 90% of what you think you want to talk about. Pick the one thing that is most important to you, and make it the through-line of your talk.
W: Some people memorize their talk, every word, I mean. Is that a good method?
M: There’s a trap in doing that, because if you sound like you’re reciting, that takes away the authenticity, actually.
W: That is a good point. A lifetime of work, condensed over a few hundred hours of prep into 12, 13, 14, 18minutes, must be quite challenging.
M: Sure. A key question to ask before you give a talk is, "Why am I doing this?" Many speakers come, thinking "This is my opportunity. I have got this agenda that I want to promote these people. "
W: I guess the smart audience will see through that in a moment.
M: Yes. So instead, think that you’re bringing a gift, and focus the whole talk on that. Every story you tell is in service of that idea, of that gift.
W: OK. Thank you for sharing your knowledge about this.
M: My pleasure.
