Have you ever wondered what separates the millionaires from the masses? By the time you finish this book, you’ll have the answers.

A child tennis prodigy, Siebold’s professional tennis career was a disappointment both to his handlers and to himself. He became obsessed with finding the missing piece of the puzzle, which he finally discovered inside his own mind. He then spent 20 years compiling this list of the thought processes, habits and philosophies of many of the world’s most successful people. This is an intensely personal book; you can feel the author’s passion of pursuit and discovery on every page.

177 Mental Toughness Secrets gets right to its point, opens like a hurricane and never lets up. The author pull no punches as he lights into his main theme, a comparison between what Siebold calls the “middle class” and “world class.” The book grabs you by the throat from the first page and won’t let go until you surrender whatever “middle-class” thought processes, habits or philosophies you may be harboring!

Most of the book’s “secrets” are spelled out in a single page and laid out in an extremely easy to read format. The text is short, bold and a little in your face. At certain points, I even found myself a little offended. Still, I came away with the sense that this was perhaps intentional: Siebold aims high and strong, daring the reader to reach beyond habit and limitation and ascend to one’s full potential.

177 Mental Toughness Secrets also contains action steps, relevant quotes and scores of useful references for further study. The author expounds on a secret and then gives you resources to learn more about it—and what resources! I’ve never seen a personal development book offer so much in the way of references to other books, websites, speakers and experts, and this information alone is worth the price of admission.

The only down side to Siebold’s book is that it’s so condensed and content-rich, it will likely take repeated readings to fully absorb all the material. My suggestion: use the book as a reference and get a copy of the unabridged 12-CD version. It’s a bit pricey, but will earn you back the cost many times over!
