Jaguar is an endangered animal. It is said that there are less than 20 jaguars in the world currently, one of which is now living in the national zoo of Peru. In order to protect this jaguar, Peruvians singled out a pitch of land in the zoo for it, where there are herds of cattle, sheep and deer for the jaguar to eat. Anyone who has visited the zoo praised it to be the 「Heaven of Tiger」. However, strange enough, no one has ever seen the jaguar prey on the cattle and sheep. What we could see is its lying in its house eating and sleeping.
Some people thought that the jaguar felt too lonely, so they collected money and rented a female tiger to accompany it. Nonetheless, it did not make too much sense. The jaguar just sometimes went out of its house with its 「girlfriend」and stayed in the sun for a while before it came back to its house again. 「It is normal for the jaguar to be lazy in this environment. Tiger is the king of forest but you simply put some small animals around him. That is why the jaguar shows no interest in going out. Why don't you put two wolves or at least a jackal around him?」A visitor proposed. Others all agreed with him and put five panthers into the jaguar's territory. Since then, the jaguar did not go back to its house any more. It either stands on top of the hill roaring or goes down from the hill strolling without sleeping all day long. It did not eat the meat provided by the zoo staff and has totally got back to its nature.
Actually, this principle does not only apply to animals, but also apply to human beings. Here is another story. There was a rich man who was selecting a husband for his only child among a multitude of pursuers. The man led all the pursuers to a river and pointed to the crocodiles, saying, 「Anyone who can swim across the river safe and sound will marry my daughter.」 Those pursuers looked at each other and no one dare take the initiative. At that moment, a man plunged into the river bravely and swam at a staggering speed to the other side. All the people applauded for his courage with great sense of admiration. Nevertheless, the man, after landing on the bank, shouted angrily, 「Who pushed me into the river just now?」
