Jin Yinan said, "if you do something difficult, you will get something." Indeed! This is also Jin Yinan's personal experience and the way to success. When Jin Yinan was young, he worked as a worker in a factory that made glass bottles. The glass bottles he began to blow and pull were all of strange shapes, and none of them took shape. He made up his mind to study hard. The meat of his three fingers was burned. Finally, he made glass bottles better, faster and more. Later, Jin Yinan was admitted to a military college and studied English with indomitable perseverance. After graduation, he taught in the University and engaged in academic research. He often studied and collected a large number of Red Army materials without forgetting to eat and sleep. He wrote many works on Red Army research without fear of fatigue and was deeply respected by the majority of readers. Many years ago, Zhai Mo, a painter and navigator, knew that it was extremely difficult and life-threatening to sail around the world alone in an unpowered sailboat, but he felt that such navigation could win glory for the motherland, conquer himself and surpass himself while conquering the sea. Therefore, in the absence of sailing experience, he bought an old sailboat and set out from Rizhao, Shandong Province for a long voyage. On the way, he experienced thousands of difficulties and dangers. When crossing the Indian Ocean, he was in the danger of being engulfed by the sea at any time when he encountered a violent storm with a wave height of seven meters. At this time, he tied himself to the deck of the ship with a sailor's knife tied to his calf. He was ready to die at any time despite the wind and waves. It took him seven days and seven nights to get out of danger. He was detained by the US army when he passed a US military base at sea. After finding out his true identity, the US Army helped him repair the ship and sent him on a friendly voyage. In a sea area of the Atlantic Ocean, although the wind was calm and the long loneliness brought him infinite fear, he survived. There was a huge shark following his boat for many days, and he was not frightened. On an island in the South Pacific, the native people were very friendly to him. The Sheikh's daughter wanted to marry him. In order to complete the great cause of sailing around the world, he resolutely "escaped". When they passed the Cape of good hope, the people there were moved by his bravery and invited him to a banquet. As he continued his voyage, all the ships that stopped there whistled for him. After more than two years of hard work, Zhai Mo finally returned to Rizhao. Zhai Mo practiced the principle that "you can get something if you do something difficult". When Darwin was young, he made great efforts in studying and studying zoology and botany. He could carefully observe some animals and plants repeatedly, and sometimes he even forgot to eat. He collected a large number of plants and insects and made them into specimens. Later, he bravely took a cruise ship to South America in Britain and went to South America alone to investigate animals and plants and collect samples. There, he lived in the open air, suffered from hunger, and experienced many risks and hardships. Through years of investigation, collection and research, Darwin wrote the great book "origin of species", which expressed the view of "natural selection, survival of the fittest", and promoted the progress of world biology. It can be said that Darwin's outstanding achievements were achieved by his bravery of hardships and the courage to do difficult things. As the saying goes: "the sword is sharpened, and the plum blossom fragrance comes from the bitter cold." If a person wants to make amazing achievements, he can't do anything difficult. Some people are greedy for comfort, do things light and afraid of heavy, for fear of suffering, for fear that they have spent more effort and brains. How can we make greater achievements if we want to do so? "Nothing in the world is difficult if you are willing to climb it." Difficult things are not difficult. As long as you are willing to do them, you will have unexpected gains. You might as well be brave and willing to do more difficult things, rise to the challenge, advance in the face of difficulties, and you will get something.
