I frequently buy this book as part of my graduation presents. I just gave a young woman this book yesterday, and told her that other than the Bible, this book has been the most transformative and important book in my life. Although its been years since I read it in full, I use its principles in my life, quote it, remember it. Thinking about buying the workbook as a refresher course for myself. Not a book to read and put down. I book to transform your life if you apply its principles in your personal life and professional life.
