This seminar is excellent. My boss sent me to this seminar, pretending a possibility in the future I may have to make a presentation by myself. In my lifetime, I totally did presentaions by myself three times. My last presentation was sixteen years ago. That means I do not have to do this for living. I am a registered Professional Engineer,senior project manager, Ph.D., very technical and not much outging person. However, I found this seminar was very helpful. It changed the way of my thinking like an eye openning. The content of textbook was properly organized. The instructor was very knowledgable and prefessional. I highly recommend this seminar to the technical professionals. However, if you are a technical person, be prepared for this class may be a little intimidating to you, pressuming that most of your classmates may have done a lot of presentations and some of them do it for living. But it will definitely change the way you work and your thinking about your work as well as people you work with in your company. It can be for both presentation skills and personal enrichment. Thanks.
