In order to make money, I spent eight years and nearly 10,000 hours, and the biggest insight I gained is: don't think about whether he's right or wrong, think about how I can make money! For example: Buffett says gold has no value, right? He believes that if it doesn't generate profit, it doesn't generate value. He is the wealthiest person in the world. The poor stay at: he's right, I won't buy. But the rich think one step ahead: gold can also go up, how can I profit? Beware of becoming a high-cognition poor person!
