A psychology professor visited a mental hospital to learn about the living conditions of the insane. After a whole day, he felt that these people were crazy and acted unpredictably, which was truly an eye-opener.
Unexpectedly, when he was about to return, he found that his tire had been removed. "It must have been done by one of those lunatics!" The professor thought angrily and began to take out the spare tire to install it.
The situation was serious. The person who removed the tire had actually removed the screws as well. Without the screws, the spare tire couldn't be installed even if there was one!
The professor was at a loss. When he was extremely anxious, a lunatic came hopping and skipping, singing an unknown cheerful song. He noticed the professor in the predicament, stopped and asked what had happened.
The professor was too reluctant to deal with him but told him out of politeness.
The lunatic laughed heartily and said, "I have a solution! He removed one screw from each tire and thus got three screws to install the spare tire.
While the professor was surprised and grateful, he was extremely curious: "How did you come up with this solution?"
The lunatic laughed mischievously and said, "I'm crazy, but I'm not stupid!"
In fact, there are many people in the world. Because they have discovered the joy in their work, they always show an unusual enthusiasm that is difficult for others to understand. When many people are laughing at them as lunatics, others might be laughing at them as idiots.
