This book changed my career. I was responsible for developing a course to teach our employees how to become better presenters. I did a ton of research, read many books, but this one was my single most used resource. The large majority of my company's training philosphies are now based on this one book. It's working for us incredibly well. I tried everything in the book that Mr. Jolles suggested. Most worked, very few didn't. Without this book I'm sure the course I developed wouldn't have been half as good as it was. We now have a staff trained using the methods Mr. Jolles suggested and with great and measured success. Thanks Robert! You have no idea what a huge impact you have had on my career and my company's profit margin! The only problem with the book is the title. You should really change it to something that describes what it's actually about. Just get rid of the "How to Run Seminars and Workshops:" part.
