The story of Sima Guang's diligence.

Sima Guang was the prime minister in Song Zhezong's time, and he once edited "As a Mirror", which was a famous prime minister at that time. When he was a child, he was worried that his ability to recite poems was not as good as others. Everyone studied and discussed together. The other brothers had already finished reciting and went to play and have a rest, but he studied hard alone until he could recite it skillfully. He himself said: "If you study hard now, you will get long-term gains. He will read the books he has recited intensively and will never forget them." After a long time, I have read all the ancient books and remember them clearly. He said, "You can't read without reciting. When you are riding and walking, when you can't sleep in the middle of the night, you can recite the articles you have read and think about their significance, and you will gain more! "
