After reading the first 100 pages I knew this was a book I wanted to own. So, I bought a personal copy on whose pages I could mark key concepts that I could go back to again and again. This is a book that will live on in my collection of what I consider to be "transformative" books. If you're not changed after reading this book, I have to wonder if your heart will ever open. And, thank you JoCo Pub Library for making books accessible.
