From The Seven Minute Star, Step 8, Delivering Great Content:
Speakers almost always say “Thank you!” at the end of their speech. But remember: You are The Seven Minute Star! Shouldn’t the audience be thanking you for your inspiring performance? Don’t worry about being perceived as arrogant when you close without saying “Thank you.” Leaving it out actually emphasizes the final point you’ve made, while using it detracts from that point — and, I would argue, from your entire speech!
Consider this conclusion:
“In my entire life I will never forget standing in that dark room in Yad Vashem, the Holocaust Museum of Jerusalem. In the center, six eternal flames, the walls of the room made up of a never-ending number of mirrors at diverse angles. There were only six flames in that room, but what I saw was an infinite number of light dots reaching into eternity, and I knew that each and every single one of them reflected the loss of one human life. This incredible experience will follow me until my very last day…. Thank you!”
Do you see what I mean? You’d simply be smothering those powerful emotional vibes you spent so much effort to create if you say “Thank you” at the end. Why would you want to do that?
Please, please don’t say “Thank you.” Say what you have to say, then take a half-step back. That’s it; that’s all you need to do. The audience will know it’s the end, and the first movement in the crowd will be applause.
