I warmly recommend this book to anyone who is suffering from shyness in any form. I immediately recognised myself in the first chapter where Mr. Carducci identifies the problem, but was so encouraged by his approach. He makes a distinction between changing yourself (I have tried to do that so many times, unsuccessfully) and changing your choices. This was a revelation to me. His approach is to show a shy person how to make better decisions and choices in everyday life. This is possible through strategies that can lead to realistic alternatives.
The bottom line, of course, is "does the book work?" I can honestly say it does, for me. It's not a magic cure. It involves work. I am still a person who tends towards shyness. However, I have learned strategies to help me overcome it. At times I forget them and go into reverse, and re-enter my own little frozen, stammering, blushing world. But then I go back to the book and re-read the underlined bits and remind myself of what I have to do to live a "successfully shy" life.
