Or NOT gotten over their shyness. The book is inspiring because you realize that 1) shyness can be overcome, and/or 2) you can succeed even in highly public fields and remain shy.
This is not the magic bullet that will tell you all you need to know about overcoming shyness, but it will inspire and motivate you. So if you are on the path to overcome your own shyness, this book is a welcome companion. I'm the author of Self-Help Stuff That Works, and I can tell you that simple inspiration and motivation works very well to keep you taking the actions that will eventually change your life. I recommend this book.
However, this is not to say that the book isn't useful. Shy and socially anxious people will likely identify with those whose words appear. It's often important for those of us with social fears to discover that others, especially those in the public eye, share our problem. Furthermore, there are a few instances where people like Dave Thomas, founder of Wendy's, offer suggestions which worked for them, relate a relevant experience, or say something poignant or significant.
Not a primer on social anxiety or "Chicken Soup for the Shy Soul," this small volume is primarily a thinking-of-you gift book.
