Presentation Zen details the presentation style of 3 gurus: Seth Godin (see video); Guy Kawasaki (see interview video and casual video); and Tom Peters (see 3 clips).
I have seen Seth live. His style is relaxed and very interactive but more importantly very concise. (Like drinking from a fire hose).
Guy is very relaxed and self-effacing. He tries to follow a Top 10 style format.
Why is Tom Peters so good? He knows his stuff. He does his homework. He’s passionate about his subject. (His PowerPoint is long!)
Want to be a good speaker? Toastmasters. Practice. Practice. And watch some great speakers and their style. (The key is confidence and you get that when you know your stuff and your have a passion or enthusiasm about it. The same tips apply to sales).
