"There is an interview by Elon Musk where he says that he learned know sending a ship to the moon with SpaceX by reading books. Now, I don't know if that's true or not. It may be true some people have the type of intelligence and genius to be able to take complex concepts out of a book and be able to not only understand them and interpret them, but to actually apply them in everyday life. But with YouTube videos, I've been able to learn everything from literally everything."
