It is very hard to tell a good story. If you tell a good story, both you and your audience win. If you tell a bad story, you have just wasted everybody’s time. This book is by far the best book that I have ever read on how to tell a story (a.k.a. make an effective presentation). It focuses on how to tell a story to an audience. Specifically, how to motivate your audience (what’s in it for them?), how to capture their attention, how to organize your ideas, and how to structure your presentation materials (both text and graphics).
If you give presentations, you need this book. It has totally changed the way I approach writing presentations.
