This TED talk from Nancy Duarte is worth a few minutes of your time (about 18:00 actually).
She talks about the structure of inspirational talks, and shows her analysis of Steve Jobs’ launch of the iPhone and of Martin Luther King’s “I have a dream” speech.
Strangely enough while she talks about the importance of story, she only tells 2 personal stories… but her research is presented like it’s a story.
