Most of Kent's ideas seem to be largely based on Tony Robbins' books "Unlimited Power" and "Awaken the Giant Within". Having already read those two books, I didn't get what I had expected from reading Unstoppable Confidence. Unstoppable Confidence does contain some useful and effective ways to improve your confidence, but the book is poorly written and organized. I was pretty disappointed in this book, to say the least. In addition to Robbins' books, I'm sure that you can find better information on increasing your self confidence.
