This is the sort of book you read multiple times because there's so much to unpack. It contains so many examples for the reader to respond to and it spurs a lot of self-reflection. I would highly recommend it. It will give you the information you need to identify the behaviors associated with emotional immaturity and describes the tools you can use to limit how much the behaviors of others impact you emotionally. I would say this book will be cathartic to many but helpful and illuminating to everyone.
