Steve Jobs' 2005 commencement address at Stanford University has been viewed more than 2 million times on YouTube. Five years after he delivered it, a text version still flies around the Web. The speech is as powerful for its message–stay hungry, stay foolish–as it is for its structure and delivery. "Today I want to tell you three stories from my life," says Jobs. "That's it. No big deal. Just three stories." And with that, viewers (and readers) are hooked.
Had to share This article from Forbes, "How To Give A Great Speech" as it is quite good, and I think that Jobs is the ultimate engaging speaker. However, using PowerPoint as I suggest in an earlier post is the combination that works. A great message presented in great style, such as storytelling with speech support to emphasize the major points.
