I just finished reading Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future . It was delightful and inspiring. I recommend it, if you are into that sort of thing. I've also read Steve Jobs and The Everything Store: Jeff Bezos and the Age of Amazon and it's even interesting how similar these guys were while being quite different. They all had different passions, upbringings, and paths to get to where they were. But they are also all highly intense, expect impossible things from their employees, have employees who develop an unwavering loyalty to them, and so much more. None of them were "nice" people in any sense of the word, although Elon definitely gets cut more slack than Bezos because he's "changing the future". If you want to catch an excerpt from the book, check it out: It's a very good representation of what the other 400 pages contain.
