德莱塞《美国的悲剧》：
Seeing and doing are two entirely different things.
看人家做和自个儿做，完全是两回事。
原文：
“Not the same thing. Not the same thing,” insisted Gilbert sharply. “Seeing and doing are two entirely different things. A person without any experience can think a lot, but when it comes to doing, he’s not there. Anyhow, this is one business that requires people who do know.”
“不一样，不一样。”吉尔伯特一个劲儿厉声说。“看人家做和自个儿做，完全是两回事。没有什么经验的人可以想得很多很多，可是一做起来，就什么都不行了。反正不管怎么说，这个工作就是需要真正懂行的人。”
