Once upon a time, there was a homeless man who was originally a library administrator, but he always put books aside to read and ignored the people who read them. He was fired after working for three months. 75 novels, 29 medical treatises, and 7 out-of-print books were stolen from the library. He was fired from his job, and 80% of the money he begged was used to buy books, and 20% was used for food and clothing. After reading the book, he would go out at the original price, so that he could continue to obtain a supply of knowledge.

One day, he spent a few yuan to buy things for submission and sent a few essays to the publishing house. Waiting for the good news, he finally got his 300 yuan manuscript fee a few days later. Then he continued to send compositions to the publishing house, and the money in his pocket became more and more. Then he published a book, which was bought like crazy and made him a millionaire. The money he gained with his knowledge should be said to be lucky, because when the editor is too busy, he will not seriously read the things written by unknown people, and they will be ignored. However, the editor picked up this composition and read it over and over again. His current achievements are the result of his hard work.

Working hard to change your destiny has become the motto for most people to succeed because they know that only hard study can change their destiny. It will also enable us to understand the rich world and learn to survive.
