This book brought joy and clarity to one who has wondered about her introverted core. For introverts, it will help them understand the depth and strengths of who they are and how that can relate to a society not necessarily like them. For extrovert readers, it can help them understand themselves better too and relate to their introverted friends, family, and co-workers. This book also can be a real eye-opener to your child's temperament, which can help in understanding your child and being more sensitive to parenting them. I highly recommend this book!
