There once was a famous professor, who always wrote the number 2 and 4 on the blackboard at the first course to his new students, and asked the students what is the answer.
Every time when he asked this question, some of his students said 6 is the key while some others hold that 2 is more proper and some of them chose 8 as the answer, moreover, there were still others who were just sitting at their seats without a word.
But at the time that the students were discussing the issues, the professor always sighed and said to the students “It is no use for you to debate because all of you did not focused the key point: what exactly the question is asked about? Do those two numbers were being to be added, subtracted or be acquired to do some other calculations? Without what the question is exactly about, how can you make a right respond”.
A man died and was on his way to another world, either the Heaven or the hell. He saw an extremely magnificent palace half way and the owner of the palace asked him to stay and live in the palace.
The man said, “I have been working arduously during my life and now I just want to eat and sleep without any work.”
The owner of the palace said, “If so, there is nowhere else better than here for you. There are a wealth of seafood and delicacies in my palace and you can eat whatever you want without anyone stopping you. Moreover, you can rest assured that nothing needs to be done by you.” Then, the man settled down in the palace.
At the beginning, the man felt very happy at the rotation of eating and sleeping. But gradually, he felt a bit lonely and void. So he went to the owner and groaned, “It is very tedious to live by just eating and sleeping every day. Now I show no interest in this kind of life any more. Could you help me find a job?”
The owner replied, “Sorry, there is no job here at all.”
After another several months, the man could not bear the present life and went to the owner again, “I really could not stand this sort of life any more. If you do not offer me a job, I would prefer to go to the hell instead of living here.”
The owner of the palace smiled contemptuously, “Do you think it is Heaven here? It is actually the hell!”
