First, challenges and opportunities are famous sayings. Hua Luogeng once said, "The inspiration of science can never wait. If there is any accidental opportunity in scientific discovery, then this kind of' accidental opportunity' can only be given to those who are literate, to those who are good at independent thinking, to those who have perseverance, and not to lazy people." Lucky timing is like a transaction in the market. If you delay it a little, it will go to fall in price. -Bacon 2 Example: The famous scientist Pasteur once told such an exciting story about opportunity: In 1822, at the end of a report, the Danish physicist Orst connected both ends of a wire that happened to be with him to a voltaic battery and placed it above the magnetic needle, parallel to the magnetic needle. At first, he deliberately made the wire perpendicular to the magnetic needle, but nothing happened. However, when he accidentally laid the wire flat and parallel to the magnetic needle, he was surprised to find that the magnetic needle was deflected in the opposite direction. In this way, relying entirely on the opportunity, Otter discovered the relationship between electricity and magnetism, and opened the way for Faraday to invent electromagnetic generators. It was in telling this story that Pasteur uttered a wise saying about opportunity: "In the field of observation, opportunity only favors the prepared mind." After Liu Bang and Xiang Yu gave up the best chance to kill Liu Bang at the Hongmen Banquet, they were forced to death by Liu Bang because they didn't get the chance to kill Liu Bang. If Xiang Yu seized this once-in-a-lifetime opportunity to kill Liu Bang at the Hongmen Banquet, their fate would be completely different and the history of China would be rewritten. Challenges and opportunities are * * *. Only in constant challenges can you find opportunities. Don't be afraid of challenges. If you are afraid of challenges and competition with others, you will never succeed. The same is true for finding a job. If you are afraid of competition with others, you may never find a job. You must be good at grasping opportunities and dare to challenge, and you will always succeed. But what is an opportunity and what is a challenge? What are the opportunities and challenges? Is opportunity greater than challenge, or challenge greater than opportunity? Under what circumstances can opportunities and challenges be transformed? This and so on really need to be sorted out. Challenges and opportunities are * * *. Only in constant challenges can you find opportunities. Don't be afraid of challenges. If you are afraid of challenges and competition with others, you will never succeed. The same is true for finding a job. If you are afraid of competition with others, you may never find a job. You must be good at grasping opportunities and dare to challenge before you can succeed. So people can't help thinking for a moment. Learning this thing doesn't matter if no one teaches you, the most important thing is whether you have consciousness and perseverance. 2 cases of hanging the beam and stabbing the stocks

In the Eastern Han Dynasty, there was a man named Sun Jing, a famous politician. When he was young, he was studious, often closed the door and kept reading alone. Reading from morning till night every day is often forgetting to eat and sleep. I have been studying for a long time, I am tired, and I still don't rest. After a long time, I dozed off with fatigue. He was afraid of affecting his study, so he came up with a special way. In ancient times, men had long hair. He found a rope and tied it firmly to the beam. When he is tired of reading, he dozes off. When his head is lowered, the rope will hold his hair, which will hurt his scalp and wake up immediately, and then continue to study.

Kuang Heng is diligent and studious, but there is no candle lighting at home. There are candles in the neighbor's house, but the light can't reach his house, so Kuang Heng chiseled a hole in the wall to attract the light from the neighbor, so that the light can shine on the book to read. There is a big family in the same town called illiterate, a rich man with many books at home. Kuang Heng went to his house to be an employee, and he didn't want to be paid. The host was surprised and asked him why. He said, "I hope I can get your book and read it through." Hearing this, the master sighed deeply and lent him the book to read. So Kuang Heng became a great scholar. Paragraph: Understanding the purpose of seeking knowledge "is to seek truth and enlighten wisdom", and master the correct method of seeking knowledge initially. "When lonely, reading can be a pastime. When talking, knowledge can be decorated. When doing things, knowledge can enhance talents. "
