There was once a famous scientist who made several important discoveries. Once he was asked how he was able to be so creative. He replied that it all came from an experience he had with his mother when he was 2 years old. He was trying to take a bottle of milk out of the refrigerator. But the bottle was too slippery(滑的) and he dropped it. The kitchen floor was covered with milk.
When his mother came into the kitchen, instead of shouting at him or punishing him, she said, "Robert, what a great and wonderful mess you have made! I have never seen such a huge puddle of milk. Would you like to play in the milk for a few minutes before we clean it up?"
So he did. After a few minutes, they cleaned it up together. Then his mother said, "This was a failed experiment(实验) in how to carry a big bottle of milk with two tiny hands. Let's go out in the backyard and fill the bottle with water and see if you can find a way to carry it without dropping it. "
The little boy learned that if he held the bottle at the top near the lip with both hands, he could carry it easily without dropping it. What a wonderful lesson!
The scientist then added that it was at that moment that he knew he didn't need to be afraid to make mistakes. He learned that mistakes are just opportunities(机会) to learn something new — which is, after all, what scientific experiments are all about. Even if the experiment doesn't "work", we can still learn something valuable from it.
