One day a rabbit ran into an elephant. "Hello," said the rabbit. "Fine day, isn’t it?" The elephant stopped to look down at the tiny(小的) creature and shouted. "Leave me alone. I don’t have the time to waste on someone so small." The rabbit was shocked by the elephant’s words. Then he decided to ask the whale(鲸鱼) what she thought about the elephant’s rudeness. But the whale laughed at this tiny animal. The rabbit said, "You think that I am weak, but in fact, I am strong! I can beat you at Tug-of-War (拔河比赛)." The whale looked at him for a moment before bursting into laughter. "Very well, little one. Go and get a rope," she said. The rabbit ran off to find a strong and thick rope. Then he went to the elephant, "Elephant, I will beat you at a game of Tug-of-War." The elephant laughed loudly, but agreed to challenge the tiny animal. He tied the rope around his huge waist. The rabbit took the other end and ran away. He called back to the elephant, "When I say 'pull’, you start pulling. "The rabbit took the other end of the rope to the whale, "Tie this to your tail and when I say 'pull’，you swim." The whale tied the rope to her tail after laughing at the rabbit’s foolishness. Then the rabbit called out "PULL!" The elephant and the whale began pulling. After a while, they were too tired to continue. The elephant and the whale never knew how such a tiny creature could beat them. But from that day on, they said "hello" to the little rabbit with great respect whenever they met.

　　Decision-thinking is not unlike. It often matters not only what you think, but also what others think you think and what you think they think you think. The mental process（过程） is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.
　　The great mathematician John von Neumann was one of the founders of game theory. In particular, he showed that all games fall into two classes; there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks; they don't win by chance, but by means of logic and skills. Then there are games of 'imperfect information', like poker, in which it is impossible to know in advance that one course of action is better than another.
　　One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse, business and life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors（因素）, as best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.
