The famous research scientist Stephen Glenn, who had made very important medical achievements. was being interviewed by a new  reporter asked Stephen Glenn so much more creative than other.

He said that it all came  from an experience with his mother that happened when he was two years old. He tried to carry a bottle of milk form the refrigerator. But tried to carry a bottle of milk sprinkled all over the kitchen floor.
When his mother came into the kitchen, instead of complaining about it ,she said , “Robert, what a of complaining about it ,she said, “Robert, what a great and wonderful mess you have made! Well, the terrible thing has already been done . Would you like to get down and play in the milk form a few minutes before we clean it up?”
Indeed, he did. After a few minutes , his mother said ,”You know , Robert , whenever you make a mess like this , you have to clean it up . We could use a sponge or a towel. Which do you prefer?” He chose the sponge and together they cleaned up the milk.
His mother. then said, “You know , what we have here is a failed experiment in how to carry a big milk bottle with two small hands .Let’s go out in the back yard and fill the bottle with water and see if you can discover a way to carry it without dropping it “  The little boy learned that if he held the bottle at the op near the lip(容器的嘴)with both hands, he could carry it without dropping it What a wonderful lesson! At that moment he knew that he didn’t need to be afraid to make mistakes and mistakes were just opportunities for learning something new.
