After a quick breakfast, I went into the lecture hall in a hurry. A famous teacher was   to the students. He was holding up a $100 bill. Then he said to the three hundred students, "Who would like this $100 bill?" The students put uphands at once. Then he said,"I am going to give this $100 bill to one of you,but , let me do this." He made the bili into a ball. Then he said, "Who it now?" The hands went back into the air. "Well," he said,,What if I do this?" and heit on the floor and stepped on it. He picked up the bill and said,"Who still wants it?" Hands went back again into the air.
"My friends," he said,"you have learned a valuable(有价值的) today. No matter what I did to the $100 bill! Many in our life, we are dropped and stepped on. We feel as if we are worth nothing. But remember, no matter whathappened to you, you will never lose your value.You are valuable to those people who love you. Your value doesn’t come from what you do or whom you know, hut who you are."
