This book is a definitive classic and is really focused on how to manage oneself in order to enjoy a productive and successful life. This goes on the top shelf along with Carnegie's How to Win Friends and Influence People for life long lessons on developing emotional intelligence and self-discipline although they were both written decades before the concept of EI was coined. Although first published in the early part of the 20th century, and while some terms are now dated, the concepts remain solid and this version has been revised with more modern stories of highly successful people. The stories which are intermixed within each chapter bring the concepts to life and keep the book lighter and more approachable. That said, this is a book worthy of study as each chapter addresses one of the key concepts or steps to leading a meaningful and productive life.
This one competes to be on any life list of personal growth/development books to study and re-read and ought to be on the mandatory read list for all youths who aspire to "do" anything with their lives - to heck with Grapes of Wrath (gasp!).
By the way, I after I purchased the kindle version, I found a hard copy abandoned along the beach bluffs and this "sign" inspired me to really dig into this book. It was nice to have the hard copy because when I find a book like this, I underline, notate and otherwise mark it up to highlight my personal take-aways. But I'm glad I also have the kindle so that I ALWAYS have it at my side. Buy both! (or perhaps you may find one in the gutter as I did).
