Musk is a living legend. No other man have changed the world we're living in so much, and we can see it with our own eyes.
The book covers several Musk's achievements, the history and the challenges that they had. So the projects are of cause SpaceX, Tesla, and SolarCity.
It is hard to believe now, but the Falcon 1 actually launched successfully only with 4th attempt. I'm astonished by how stubborn the people behind SpaceX, and Musk, especially, was.
This is the energy that can move mountains, and I want to believe, that someday it will.
