I am almost done reading Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future by Ashlee Vance. It’s interesting, but sometimes the writing is irksome. Then again, so far, the things I’m learning from it outweigh the bad. One cool thing I learned was that before he went into the rocket-making business through SpaceX, Musk only knew how to code as he came from PayPal and other internet companies. He then turned to textbooks to read about rockets and talked to people in that industry. After a visit to Russia, he made an entire spread sheet detailing how their team will make a rocket and the cost that it will take to make it. His colleagues were impressed. “Where did you get this, Elon?” they asked. He figured it all out by reading books and talking to people.
