What does the story of the scholar going to Beijing to catch the exam tell us?

This story tells us that everything has two sides. Thinking from a positive and optimistic perspective often leads to a good ending. Why do different ideas have different results for the same thing? It's still a matter of mentality. A person who keeps a positive attitude towards life, his mentality is like the sun, where it shines. A person who has a negative attitude towards life has a mentality like the moon, and the first day is different from the fifteenth day. In dealing with all aspects of life, what kind of ideas you have, what kind of future you have.

Original story:

There was a scholar in the Qing Dynasty who failed the exam twice. I took the exam in Beijing for the third time and lived in a shop where he often lived. Two days before the exam, he had two dreams. The first dream is that he grows cabbage on the wall. The second dream is that it is raining. He is wearing a hat and an umbrella.

These two dreams seem to have some profound meanings, so the scholar went to the fortune teller to interpret them. Hearing this, the fortune teller patted his thigh continuously and said, "You'd better go home. Think about it, isn't it futile to grow vegetables on high walls? Isn't it unnecessary to wear a hat and an umbrella? "

Hearing this, the scholar was disheartened. Entering the store, he packed his bags and was ready to go home. The shopkeeper was surprised and asked the scholar, "Isn't there an exam tomorrow?" How did you go back to your hometown today? "

In this way, the scholar told the fortune teller's dream interpretation, and the shopkeeper was very happy: "I can interpret dreams, too." I think you must stay this time. Do you think that planting vegetables on high walls is not a high kind (middle)? Doesn't wearing a hat and an umbrella mean that you are prepared this time? "

Hearing this, the scholar felt more reasonable, so he took the exam happily and was on the list.
