Query: Great Anger Management!

This book is wonderful. It's actually more of a workbook, rather than a book to read. It really helped me. Step by step instructions and techniques are in-depth and the extensive examples really help put things into perspective. Overall, I would recommend this book to anyone who is looking to manage their anger or simply calm it down. This book really helped me understand why I was getting frustrated and angry and assisted in helping me implementing it into my daily life.
