A teacher began his class by holding up a glass of water. He asked the students, "How much do you think this glass weighs?"
"Fifty grams(克)!" "One hundred grams!" "One hundred and fifty grams!" The students answered. The students took great interest in guessing.
"I don't know either." said the teacher. "What would happen if I held it up like this for a few minutes?" "Nothing," the students said.
"OK. What would happen if I held it up like this for an hour?" "Your arm would ache," said a student.
"You're right. Now what would happen if I held it for a day?" "Your arm would go numb(麻木的). You may have to go to hospital!" said another student, and all the students laughed.
"Very good. But during all this, did the weight of the glass change?" asked the teacher. "No." "Then what caused the pain and numbness?" The students were confused.
"What should I do now to get rid of the pain?" asked the teacher again. "Put the glass down!" said a student.
"Exactly!" said the teacher. "Life's problems are something like this. Hold them for a few minutes in your head and they seem OK. Think of them for a long time and they begin to ache. Hold them even longer and they begin to make you numb. You will not be able to do anything."
The students learned a truly important lesson. It's important to think of the worries or problems in your life. But what's even more important is to "put them down" at the end of every day.
