This book has been one the most influencing books I've ever read in my life. It gave me a good understanding of the "problems" many parents and/or teachers have when it comes to deal with kids, youth, or adults with ADD. As I believe there is not a "china's wall" between all sorts of psychological and mental disorders, understanding the illustrations given in this book has given me a whole new vision and a powerful tool to look into the complexity of people's minds including my children, and myself. I wish I could afford to buy and donate at least one copy of this book to every single school in Vancouver and even in all over the world. This does not mean that Dr. Gabor Mate has completed all the things to be said to to be known about ADD, but definitely he has done a great job in providing a well factual supported points and ideas in a well illustrated and understandable book usable for average readers who don't know a lot about psychology. I would like to visit Dr. Gabor Mate in person and express my regards as well as discuss my understanding of his book with him.
