*I received a complimentary copy of this book from Booksneeze.com for an honest review. I was not persuaded in anyway to give a positive or negative review. The words are my own.*
That said, there are some basic principles that could help those who are not in a speaking position. Tips such as being specific, word selection, and proper use of humor can benefit almost anyone. As the saying goes, "It is a wise man that use two words when most use three."
However, while some of the book is applicable to everyday situations this book is not designed for those who are struggling with relational communication problems. If you desire that seek another book.
I have heard Mr. Davis speak and have also purchased his SCORRE speaking course on DVD. This book is an excellent resource to compliment that course. If you are speaking in public or have a desire to do so get this book and the DVD course.
