A great read; very engaging, wonderfully written. Hats off to Elon Musk for allowing Walter Isaacson to shadow him for 2 years and have full unedited control of what he wrote and how he wrote it. This is a very revealing book about Musk's complex personality and how he interacts with people - those close to him, and not. We are often under the impression while reading that Elon Musk is headed for a nervous breakdown. As he insists on having such a high degree of control in all of his undertakings, let's hope that a plan is in place if he ever does need to take a 'time out'. In the meantime, get us to Mars Elon Musk!
