In a book written by Bloomberg technology reporter, Ashlee Vance, about Tesla’s CEO, Elon Musk, it was revealed that Elon is very committed to his work and making the world a better place. Elon Musk is the entrepreneur behind some of the big companies like Tesla, Space X and PayPal.

In another book titled “Elon Musk:Tesla, SpaceX and the Quest for a Fantastic Future”, it was mentioned that there was a person who has worked with him said that Elon Musk works for 23 hours a day. On top of that, in Vance’s book, it was written that once Musk even scolded one of the Tesla’s employee for missing an event just because the employee went to see the birth of his own child.

In the email Musk mentioned that there was no excuse and that he was extremely disappointed. On top of that, he advised the employee to figure out where his priorities were. He also added that they were changing the world and changing history and he wanted the employee to choose whether he was willing to give his commitment or not.

In the book, it was also written about his personal life. In the early days when an employee complained that they were working too much, Musk replied that he told them that they would get to see their families a lot when the company went bankrupt.  This according to Ryan Popple, one of Tesla’s employee in the earliest day who is currently the CEO of Proterra, an electric vehicle manufacturer.
