 The singular skill that you can learn that's the most statistically proven way to create long-term wealth in your life is to know how to close deals and sales skills and business skills. Everything else is kind of a subset to that. If you look at somebody even like Elon Musk, you don't see this because he mostly talks about SpaceX and Tesla, but he knows how to close deals. He didn't start PayPal. He merged PayPal. He closed a deal to merge PayPal into somebody else's brand that had started PayPal. When you look at Tesla, he didn't start Tesla. What did he do? He bought Tesla from two brothers who had started Tesla. So he's a deal maker.
