Can I give this 6 stars? I read Quiet by Susan Cain as well, and it was interesting to learn about the way introverts' brains work. This book, however, gives solutions to the problems social anxiety causes. The approach is friendly and funny. This is clearly coming from someone who knows exactly how we feel and what to say to inspire us and give us confidence. It's a toolbox of helpful material - little step-by-step (and realistic and specific) things we can do to make life easier and more enjoyable.
