I do quite a bit of public speaking. At one time I spent six months with a TED talk coach. I believe the TED folks have dove very deep into what makes a compelling presentation, especially of an idea. And most talks are really selling ideas, getting buy in from the audience on something in a way they were not previously thinking about.
These are the four most important takeaways from that coaching.
- Practice out loud. In front of a mirror.
- Few slides as possible. One to three.
- Care. About your subject. About your audience. (see #4)
- Honor the time your audience is giving you. Give value.
