A young man once asked Albert Einstein what the secret of success was. The great scientist told him that the secret of success was hard work.

A few days later the young man asked him the same question again. Einstein was very annoyed.

He did not say anything but wrote a few words on a piece of paper and handed it to the young man. The young man looked at the piece of paper. On it was written:

X=Y+X+Z

"What does this mean?" asked the young man.

"A means success," explained the old scientist. "X stands for hard work, Y stands for good methods, and Y means that you should stop talking and get down to work."

有个年轻人曾经问阿伯特.爱因斯坦成功的秘诀是什么，这位伟大的科学家告诉他成功的秘诀是勤奋。

几天后这个年轻人又问他同样的问题，爱因斯坦很恼火。

他一句话也没说，只是在一张纸上写下几个字，递给那年轻人。年轻人看了纸条，只见上面写着：

X=Y+X+Z

“这是什么意思？”年轻人问道。

“A表示成功，”这位老科学家解释说，“X代表勤奋，Y代表好的方法，Z的意思是别空谈，认真的工作。”
