"Many things grind" is a famous saying, which tells people that nothing can be done as long as they are diligent.

For example, Sun Jing, a Jin Dynasty man, tied a rope to his hair every night and tied the other end to the beam in order not to doze off. Every time his head droops, the rope will wake him up and continue reading after waking up. In this way, he became a celebrity who used a hanging beam to prevent himself from falling asleep. Su Qin, who is also a spy, has been looked down upon by others because he can't be an official in Qin. So he decided to fight for breath. From then on, he studied hard and forgot to eat and sleep. Whenever it's quiet at night, Su Qin is already dizzy and always wants to sleep. He immediately stabbed his thigh with an awl and felt pain, and people woke up. This is Su Qin, a celebrity who woke himself up by stabbing stocks.

Another example is Kuang Heng in the Western Han Dynasty. His family is poor, but he likes reading very much. However, at night, there was no oil lamp in his house, and a lamp was lit in his neighbor's room, so Kuang Heng dug a hole in the wall and read by the light coming out of the hole. This is the story of "digging a wall to borrow light".

There is also the modern Xu Beihong, whose paintings are well-known at home and abroad. When he was young, he inspired himself to learn painting, won glory for our country with his own efforts, and prevented foreigners from looking down on us in China.

From these celebrity stories, everyone must have learned a truth: only by persisting in the end can we make a difference.

You can't do anything half-heartedly, half-heartedly, but you must finish what you started and persevere. Only in this way can we make a difference and make due contributions to the people and society.

Lincoln, the first 16 president of the United States, was a world-famous great orator. His success lies in that he has been practicing his eloquence since his youth, watching and listening more. When he was young, he worked as a farmer, lumberjack, shop assistant, postman, land surveyor and so on. In order to become a lawyer, he often walks 30 miles to a court to listen to lawyers' arguments and see how they argue and gesture. He imitated politicians and speakers while listening to their impassioned speeches. He listened to the evangelists who traveled everywhere, waved their arms and shook their voices in the sky. When he came back, he followed their example and practiced his speech repeatedly in the Woods and cornfields. The success of the speech made Lincoln finally become an eloquent lawyer and finally entered politics.
