The author's theory is that most theories about how to achieve success are fundamentally incorrect One thing that he thinks is missing is little attention to the need to take risks and step outside one's comfort zone.
His ideas have some weight to them, because he himself rose from a difficult childhood as an immigrant whose mother had a mental breakdown, and was raised in foster homes, finally graduating college. He had several successful and failed businesses but always rose to success.
He sprinkles the information about the plan towards success with stories both positive and negative illustrating his principles, of famous people from many walks of life from ancient history through present time from a variety of backgrounds.
For me, the ideas were not stunningly original, and they do, in fact, mirror Agile methodology. They dovetail with several of my recent readings in that making experiments, even if they are mistakes, are necessary for continual improvement.
This is a reasonable book to read to keep yourself psyched and on the journey to success. Defining success is sort of an epilogue in the book. He doesn't define it as money or fame, but rather advocated defining it as satisfaction.
This book will only seem revolutionary if you are of a mind set that says only hard work and talent are necessary for success. Otherwise, if you already know this, it is just a nice inspirational book. I have nothing against inspirational books and it's good to be reminded of the importance of stretching yourself and taking risks.
I recommend this book for anyone who likes a good read about success and risk taking. It was a nice add this year to my other self improvement reading. It's not very long and the stories make it go down easily.
