 You don't have to learn how to swing a hammer. You need to learn how to coordinate and manage humans. And Will Durant, who I think is the wisest person, I saw Elon Musk recently, started telling everybody to read Will Durant. I was like, I've been telling people that for 10 years, Elon, I got your beat on that. But Will Durant says, the men who manage men will always manage the men who can only manage things. So if you can manage humans, you'll do better than if you're just somebody who can just manage a thing like I swing a hammer. Of course, Will Durant also said, and the men who manage money manage all. So eventually become a capitalist.
