There is a short story: there is a tall and solid reef standing by the sea, and the waves keep hitting it every day. The proud reef shrugged off the waves and said with a smile, "You little spray, how can you knock me down?" It's a waste of effort. "The small waves didn't waver, but they kept hitting the rocks day and night. Day after day, year after year. Many years later, these huge rocks became loose. When the small waves hit the fragile reef again, a miracle appeared and the reef was knocked down. Small waves can knock down rocks, by what? Undoubtedly, it is unremitting efforts and accumulated success. As Lu Xun said: "if you work hard, you will get something." Over time, from less to more, miracles can be created. "In fact, knowledge is also indispensable in the process of accumulation. Learning is not a one-time action, but a long journey. Scholars and successful people all over the world always pay great attention to accumulation, and knowledge is accumulation. For example, Strange Tales from a Lonely Studio written by Pu Songling, a famous writer in Qing Dynasty. It is not only Pu Songling's masterpiece, but also the result of his painstaking collection of information. After several failures, Pu Songling was completely disappointed with his career, so he devoted himself to writing in seclusion and decided to write a work with ghosts and gods as the theme to expose the dark social life. Although he knows some ghost stories, writing serial stories is like nine Niu Yi hairs. So he set up a tea stall on the roadside, and pedestrians who can tell ghost stories can have a free tea break. In this way, Pu Songling not only accumulated a lot of creative materials, but also learned about the local conditions and customs at that time, and finally created a book "Loneliness and Anger" with "writing ghosts and writing demons" and "stabbing greed and abuse". Wang Xizhi's "water has means to cover up" can also give us enlightenment. Wang Xizhi, known as the "Book Sage", was determined to cultivate his son Wang Xianzhi into a famous calligrapher like himself after having him, so he began to teach him calligraphy when he was eight years old, and strictly required him to practice calligraphy in Linchi every day. After a long time, Wang Xianzhi was a little impatient and bored, so he asked his father what simple and quick ways to learn calligraphy. Wang Xizhi pointed to seven large water tanks in the yard and said, "Water is self-sufficient. When the water in these seven tanks is finished, you will know the secret of success. Wang Xianzhi did as his father told him. When all the water in the seven tanks was used up, he realized that accumulation and exercise were the only way to succeed. Jia Lanpo said, "Learning is like snowballing. The bigger it gets, the better it melts. "Knowledge is accumulated bit by bit. Over time, you will become a learned person. It is impossible to master all the knowledge in one day without paying attention to the daily accumulation. Therefore, to master knowledge, accumulation is the only way.
