Most contemporary PD authors and teachers credit this little book for providing foundation to their principles. It is a set of philosophical musings on the power of our thoughts. Earl Nightingale, widely regarded as the father of modern day personal development, in his best-selling recording, called the ideas in this book, "The Strangest Secret". The secret, he said, is "we become what we think about".
