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.
Anthropologists give Carlos Castaneda a lot of shit because he never produced or revealed the true nature of his sources. They think he made it up. And they act like that is an attack! If he made all this up, this dude is a philosophical GENIUS.
You are in any position where the mechanism of power has influence on your life. If you desire to advance your career, further your standing in a personal relationship, climb the corporate ladder, be an effective leader, or survive and defeat an antagonist, this book is a MUST READ.
Mastery takes you by the hand on a tour of history, your tour guides being the great masters themselves-- Leonardo Da Vinci, Einstein, Freddie Roach! You learn from their successes and failures and have the blunt and poignant insight by Greene on how to apply them to your own life. If you don't want to read this book for yourself, read it for everyone whose life you will touch. The positive energy of being on your path to mastery is contagious, and for the world to change, we need as many on their way as possible.
