I want to explain: people need goals so as not to go with the flow. The story of polar bear is a prophetic story in northern Europe: an Icelandic named Wudang intends to auction a polar bear he captured. Under the competition of many Nordic leaders, the Danish king won the deal because he contacted Wudang first. Wudang excitedly took the polar bear all the way from Iceland and prepared to go to Denmark for compensation. Wudang must bypass Norway on the way. At that time, Halad, the king of Norway, was also salivating at this polar bear, and specially asked people to take Wudang into the palace to buy this rare treasure. Wudang, who received high-standard courtesy, was unmoved and clearly told King Harald that the bear must be sent to Denmark. Halad said angrily to Wudang, "In that case, please tell me how much the Danish king spent on this polar bear when you return to the city. A few days later, Wudang successfully completed the transaction and met King Harald again on the way back. King Harold asked Wudang, "What did you get from the Danish king when you sold that bear?" Wudang replied, "The King of Denmark said thank you to me." Halad said, "If I were you, I would do the same. Did you get anything else? " Wudang said, "Yes. The King of Denmark gave me a sum of money for my next pilgrimage to Rome. " Halad said, "He is really a devout believer. But even if he doesn't sell bears to him, he often subsidizes pilgrims. Didn't he give you more? Wudang replied, "The King of Denmark gave me a very high gift and said that he planned to write me down in the history books of their country." Halad said, "What else?" Udang said: "In addition to money, the King of Denmark gave me a boat that I have never seen before in Norway. This is a symbol of great honor, but in fact I got more. The king of Denmark gave me another leather bag full of silver coins. He said that if one day this ship unfortunately sinks to the bottom of the sea, if I can escape, at least I won't end up with nothing. " Halad said, "How generous! Udang said, "I don't know if I can get more." I think it would be great to get a boat. Halad: "Did you get more?" "wudan replied," yes, your majesty. The king of Denmark finally put a gold bracelet on me. He said that a person may lose all his wealth because of an accident. But as long as he survives, this gold bracelet will always follow him. The king of Denmark also said that he would only give this gold bracelet to people like him or better. " Udang finally respectfully said to King Harald of Germany, "Your Majesty, today I want to dedicate this gold bracelet to you, because you could have easily taken the polar bear from me. "
