This small book is action packed, and well worth a read for those who want to make their presentations more lively and engaging. Jerremy Donovan has looked closely at what makes for a successful TED talk (as rated by the number of viewings), and provides us with a useful breakdown of features.
Perhaps as importantly, Jeremy has highlighted what does not work, so we are left with a reasonably clear framework of what has been shown to work. This is not a step by step to success, we are left having to craft our own presentations, and rightly that still leaves us with scope to put our personal stamp on what and how we present, just framed in a way that gets the message across in a meaningful way.
If there is one key point missing (hence the four not five stars), is that public speaking is a practical sport, and to be comfortable on stage means plenty plenty of practice (and I mean giving lots of presentations not just practising one speech), so that we are not only comfortable with what and how we are going to say something, but also have the skill and confidence to hold the floor. If you are looking for a safe public speaking club - try Toast Masters - where you can learn and be encouraged to try out all manner of public speaking formats ever before you get to the big stage and even bigger audience.
Jeremy's book definitely a good buy, but count on it as part of the journey rather than an end goal.
