Saunders, a teenager, often worries about many things. He often feels sorry for his mistakes; After handing in the examination papers, I often can't sleep at night, fearing that I won't pass the exam. He always thinks about what he has done and hopes that he has not done it; I always recall what I said and regret not saying it better.
One morning, the whole class came to the science lab. Mr. Paul? Brandwell put a bottle of milk on the edge of the table. Everyone sat down and looked at the bottle of milk ... after a while, Paul? Dr. Brandwell suddenly stood up, slapped the milk bottle in the sink and shouted, "Don't cry for spilled milk."
Then he told everyone to go to the pool and have a good look at the spilled milk bottle.
"Take a good look," it said to everyone. "I hope you can remember this lesson all your life. This bottle of milk is missing-you can see that it has leaked out at this moment. No matter how anxious and complaining, there is no way to save another drop. As long as you use a little thought and take preventive measures first, that bottle of milk can be recovered. But it's too late now. What we can do now is to forget it, put this matter behind us and focus on the next thing.
Yes, why waste tears? Of course, mistakes and negligence are our fault, but so what? Who hasn't made a mistake? Even Napoleon lost a third of the important battles. Maybe our average record will not be worse than Napoleon's, who knows? Besides, even if all the king's military forces are used, the past cannot be redeemed. So let's remember this simple truth: don't cry for spilled milk. Even if you can read all the books on anxiety written by scholars of all ages, you won't see more simple and useful cliches than "cross the bridge when you come to it" and "don't water under the bridge".
Simple truth: don't cry for spilled milk.
