I’ve long been an admirer of Steve Jobs, not least because he was the best presenter I’ve ever watched. His addresses were so effective the term “Stevenote” was coined in recognition. This TEDTalk by Nancy Duarte is useful for anyone who needs to get their ideas across, and hopes to do it with the same amount of “Reality Distortion Field” as the late, great, Steve.
