Diligence has three advantages.

Wang Xizhi, a great calligrapher in the Eastern Jin Dynasty, asked himself to practice calligraphy every day. After practice, he washed his brush in a pond near his home. Day after day, he dyed the water in the whole pond black. It is precisely because of Wang Xizhi's persistence and diligence that he is called "the sage of books". Su Qin, who was looked down upon after returning to China because he couldn't get an official position, worked hard day and night to study books on the art of war such as Six Pagodas and Yin Fu. Whenever he is dizzy and sleepy in the dead of night, he pokes his thigh with an awl to wake himself up and read. It is because of Su Qin's diligence that he finally achieved something and became a famous political activist in the Warring States Period. From the examples of the ancients, we know that if we want to succeed, we must work hard, because diligence is the foundation of success.

Tong Dizhou, a famous biologist in China, failed the exam in middle school. The teacher asked him to repeat the grade, and his classmates laughed at him, but instead of being pessimistic and disappointed, he studied hard and finally achieved excellent results. When he went abroad to study, he studied hard, won the favor of China people and became a famous biologist in China. Madame Curie, a scientist, is also tireless. She discovered radium through diligent exploration and made great contributions to mankind. Although Zhang Haidi, who is physically disabled and determined, has never been to school, she has worked hard to overcome unimaginable difficulties and successfully conquered several foreign languages. Isn't it the result of hard work that they can achieve such achievements? I wonder, if they hadn't been diligent, would they have achieved today?

Success is always inseparable from diligence, as Gorky said: "Genius comes from diligence". It is because of diligence that Sima Qian wrote the great literary work Historical Records. It is because of diligence that Chen Jingrun won the "Pearl in the Crown" and became a famous mathematician. It was because of diligence that Madame Curie discovered "radium". Diligence is an important guarantee of success. As the saying goes, "Nothing is impossible". As long as you are diligent, nothing is impossible.
