Dare to speak
Tactic number 7
'People who know what they're talking about don't need PowerPoint'.
Be rock solid on stage. Don't use PowerPoint, Prezie or Youtube videos. You can show a product, or a photo or a map. But don't lean on it. Make sure you know the speech by heart. In the book The Memory Palace by Joshua Foer you can read how speakers and actors have done this over the past thousands of years.
