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:A=X+Y+Z“这是什么意思?”年轻人问道 A young man once asked what the secret of Albert Einstein’s success was. The great scientist told him that the secret to success is diligence. A few days later the young man asked him the same question again. Einstein was very annoyed. He did not say a word, just wrote a few words on a piece of paper and handed it to the young man. The young man read the note and saw it read: A=X+Y+Z. “What does this mean?” the young man asked.
