Were you aware that Abraham Lincoln suffered from a crippling depression his whole life? That didn't stop him from being the President, winning a war, abolishing slavery, and generally being one of the baddest human beings to exist. In fact, honest Abe credited much of his success to his affliction. His obstacle was turned into his greatest strength. And that is what this book is about. We all have obstacles, but to be happy, successful, and win at life we have to learn to turn challenges into advantages.

Ryan helped one of my favorite authors, Robert Greene, write some of the most influential books I have ever read. His style is reminiscent of Greene's, and the historical references are incredible as could be expected. I definitely recommend this book to everyone.
