Principal argument: Cherish time

1. Saving time, concentrating, and studying hard are a good way to learn. ——Cai Shangsi (modern historian) 2. Concentrate your energy on valuable things, and put aside everything that is not good for you and is not suitable for you. ?——Goethe

Example

1. Lu Xun once was too focused on reading. After his family brought him a meal, he actually put the ink cartridge on the table into his mouth while he was reading. Later, people laughed at him, and he said, I just need to eat more ink

2. Did Newton boil his watch like an egg? Newton's talent was not obviously superhuman, but he was particularly diligent in studying. He devoted himself to study and research to the point of obsession. He often stayed in the laboratory for weeks at a time until the experiments were completed. Once, he was obsessed with experimenting and actually put the watch into the pot like an egg to cook. Another time, Newton's friends came to see him. After he put the food on the table, he went into the laboratory again. This friend got impatient and started eating first. After eating, he left without saying goodbye. After Newton finished the experiment, he came out, looked at the dishes on the table, and said with a smile to himself: "I thought I hadn't eaten yet, but it turns out I've already eaten!" Then he walked into the laboratory again. 3. Dong Zhongshu did not visit the garden for three years. Dong Zhongshu concentrated on his studies and worked tirelessly. Although there was a garden behind his study, he concentrated on reading and studying and did not take a look at the garden for three years. Dong Zhongshu was so dedicated to studying knowledge that he became a famous thinker in the Western Han Dynasty.
