When you wonder whether you need to something, that means it is time that you should do it. I forget who said it but I consider it of great value.
In the story, the two little mice took action immediately, running through the maze and trying to find new cheese. At last, their efforts paid off and they found a new cheese station. Furthermore, they didn't fear the cheese would disapear again because they were well prepared to face any likely change to come.
Meanwhile, the two little people were having a hard time recognizing the fact that the cheese had gone and held the belief that someone would put the cheese back. Every day they would come back to the C station and waited, hoping for the cheese turning up again. When that didn't happen, they began to complaining and even blaming each other. As a result, they were extremely upset. Finally they decided to do some research on finding the cheese in the station C and dug the wall here and there. They believed the cheese hadn't gone far and was still in the station. They worked hard but in vain. Each time the one of them wanted to go out for new cheese, the other would say something to discourage him, so it took a long time for them to make the right decision, because they had too many fears, such as getting lost and where to find the new cheese.
To our relief, they finally made up their minds to go out in search of new cheese and even imagined a wondetful picture of the dilicious new cheese.
