I am not much of a body builder (I love to lift, but I'm not that devoted), but a lot of what Arnold says in this book resonates with me. The autobiographical parts talk a lot about self-discipline and defying others' expectations to go on and make something of yourself - to live your dreams. I think this is the best lesson this book has to offer.I think every athlete should read this book at the very least. Or anyone who just wants to do something special with their life.
