WCP: "20 Rules of Money" - Patrick Bet David

Rule #1 is the most important one,  and it's the one you have to buy into immediately. It's very simple. You may want to fight it, but regardless of what you do, it's a rule. And the rule is that money is a game. The great thing about any game is that no matter what game you play, you eventually get good at it. If I've never played chess, and you've played it 100 times, you're probably going to beat me. If I've played Monopoly 1,000 times and you've played it three times, I'm probably going to beat you. So the great thing about the money game is that it can be learned."
