With complete certainty, I can tell you now - from my more than half-century of existence:
Any and all successes, as well as all my disappointments are directly traced to the principles in this book.
For any set-back or failure, I either didn't know these principles, didn't understand their power, or simply ignored them.
For every success, I have tracked back to taking these exact steps laid out in this book - to achieve, acquire, or attain whatever it was I wanted to be or have.
And that experience is why I'm bringing out this short book you can have to carry with you and review regularly.
Inside Earl Nightingale's original "Strangest Secret" recording, he mentions several books that support these ideas. If you put them together, the length is around 700 pages of text.
What you are reading here is around a hundred.
And this is designed to be slim and still contain the power of the best references that can educate and reinforce the key success principles Nightingale recorded in 1956.
