Elon Musk: How the Billionaire CEO of SpaceX and Tesla is Shaping Our Future

This one I picked more out of curiosity than the desire to learn something specific, and yet it taught me the value of courage. Musk is not the manager I think people should be, nor he is someone whose success would be easy to imitate. But he did have courage when he invested almost ALL he had made from selling PayPal to eBay to pursue his vision, and nearly went bankrupt to help Tesla in a moment of financial distress. I deeply respect that.
