不容易指的是看懂生意不容易,简单说的是只有看懂生意是重要的。别人怎么看跟你有什么关系?当股票下跌的时候,你心里充满了恐惧,那就说明你买了你不懂的公司。
Not easy means it's not easy to understand a business. Simple means that only understanding the business matters. What others think has nothing to do with you. When a stock falls and you're filled with fear, it means you bought a company you don't understand.
