A heplful guide, full of commonsense advise, but not really better than dezens other on the market. If you need a guide however and this is what is available to you, take it, it will be definitely helpful.

This short book is divided into 21 sections.
You'd think there would be 7 sections given the title.

So what are the 7 deadly sins?
The author leaves it up to you to decide.
He gives you 21 options.

At the end of every section, there is an ACTION POINT. It's another word for TAKEAWAY.

For example, one action point is, "Use your eyes to 'lock in' audience rapport."

It takes about one hour to read this book.
You could make reading this book extremely fast by just jumping to the end of every section and reading the ACTION POINT.
If you don't understand it, then you can skim the chapter.

There are better books about how to give a presentation.
Consider TED Talks: The Official TED Guide to Public Speaking instead.

This book has good thoughts and pointers about presentations. I recommend it.

This book is a helpful guide to anyone who has been asked to make a presentation or speech in front of a group of people. Scenarios are laid out in a simple and informative way to give the reader a better understanding of what may go wrong and how to avoid the obvious pitfalls. The 21 lessons that are covered in this book should be sufficient for anyone who is serious about improving their presentation skills.

I found this a very informative book with 21 lessons that are short and snappy, getting the main point of the lesson over without getting too heavy. Summed up with a quick 'Action Point' at the end of each lesson was a great touch to confirm what had just been read.
I thought the book would be enjoyed by those new to presenting with great hints and tips as well as for those that have been presenting for years who may just need a refreshing reminder of things to remain aware of.
Written in a style that was far from boring made this book an enjoyable and valuable read.
