Since I didn't read this book until now, I'm not sure how I would have experienced it sooner. I'm tempted to say that until now I needed more "howto" books while I learned how to present useful content in a way that attendees could understand and use. The horror stories in this book might have been a bit alarming had I heard them sooner, and I was lucky enough that I've had people around me sort of drip-feeding a lot of this advice as I went along. So if you do get the book as you begin to speak then let me know what you think - and read it again in another 2 years.
