Query: This book has changed my life!

Insightful and easy to understand. This book provides a clear message but still places the power of wisdom and change within the individual. The changes I've personally experienced in practicing the four agreements in every moment have coincidently caused family and friends to also take notice and ask "What is so different about you?" I highly recommend this book to everyone in which I have the opportunity to do so.
