A friend told me yesterday that she was getting ready to make a series of presentations for work and turned to several of the TED videos I have posted on this site for a refresher. Perfect. That is the perfect use for this material.
Everyone can learn a lot, so much that it is difficult to measure, from watching any one of the people who are the stars of public presentations. Each presenter featured on this site offers something different. An expertise outside of our own. Or supplementary to our own. All offer fascinating material or information.
But it is the presentation itself that I want you to learn from. How do they do it? Why that outfit? Why those words, those slides, that movement across the stage? What makes a Tony Robbins talk so big? (Why we do what we do) Why is Elizabeth Gilbert (Creative Genius) so compelling? Why do we like David Pogue (David Pogue On Cool Tools) or Seth Godin? What is the best way to use notes or slides in your talk - see TED Talks - Taryn Simon ?
You can become a better speaker by watching and thinking about the techniques of those who do it well. Find sources and study them.
