Show and Tell: How Everybody Can Make Extraordinary Presentation
By Dan Roam
I've been using the approach outlined in this book for years now, thanks to some fantastic mentors at work, but I only just got around to reading it. I don't know what took me so long to get to it - it was great, and it only took me a little over two hours to read even taking a lot of notes. The basic premise of the book is that you should tell the truth, you should tell it as a story, and you should present the story with pictures as much as possible. It goes into more detail on how to make all of that happen of course, but if you're only ever going to read one book on how tell a story that people will care about, read this one. The four presentation Storylines (Presentation Underlying Message Architectures, or PUMAs) are worth the price of admission alone.
