If you pay me ten thousand dollars a month to work for you, I'll work for you and I'll think "I'm doing it for ten thousand dollars a month, that makes a lot of sense," but if I do it for nothing then I have to ask myself, "Why am I doing it?"

如果你一个月给我一万美元帮你工作，我会为你工作，但我会想,”我是为了一万美元才做的，这样更合理“,但如果我一点报酬都没有，那我就会问我自己，”我为什么要做这份工作？”
