There is a cartoon in which a man wants to dig a well, but after finally digging five pits with different depths, he leaves a sentence, "There is no water here, so dig again in another place!" " "Sweet words and roared off. Is there really no water underground? In fact, under the soil layer, a clear groundwater is flowing quietly. What's more, some pits are close to the water surface. As long as you insist, the digger will get what he wants. To tell the truth, the well digger in the painting is not a visionary who just talks and doesn't do it. You can see that he has worked hard by holding his trouser legs high and sweating like a man. The rhetoric of "digging in another place" is proof. However, at this rate, he certainly didn't find anything except leaving a few more holes in the ground. Why? Because he lacks the word "focus" himself. Xunzi's "Persuade to Learn" has a saying: Earthworms have no advantage of minions, and their bones and muscles are strong. They eat the earth, drink the yellow land, and are also diligent; Crabs kneel six times and squat twice. It's not that there is no sustenance in the snake hole, but also impetuous. "Emphasis is on the principle of single-minded learning. As far as digging wells is concerned, make sure there is water underground. Explore more and dig more. For scholarships, if you have a clear goal, you should persevere. Many people are interested in learning. Today's physics, tomorrow's chemistry, they want to trust others in the literary world for a while, and then they want to give orders in the business world ... However, everything is almost anticlimactic, but the result is nothing. In fact, what in the world is given at one stroke? Digging a well is like this. Study your running. The deeper you learn any subject, the harder it is to make progress, and you can't become everyone without hard work. If Demosthenes doesn't practice hard with a stone in his mouth every day and recite it with the wind, how can he overcome his stuttering and become a famous speaker? If Chen Jingrun devotes himself to number theory year after year, how can he win the glory of "the jewel in the crown of mathematics"? Only dedication can be persistent. Leaving a single-minded heart is just an excuse for a half-hearted person. Such a person can be a "saint" with half a bottle of vinegar. If he wants to be an expert, why not talk nonsense? In fact, when it comes to the lack of "determination", everything is abandoned halfway, mostly because of lack of trust. Like a well digger. After digging several places without water, he lost the news that he was getting deeper and deeper. He left under the pretext that there was no water here. Although his behavior is not desirable, it is excusable because water is hidden underground. He can't judge. But when it comes to learning, first of all, everyone knows the value of what he has learned. However, after some efforts, they did not achieve the ideal harvest. They began to doubt, doubt the value of learning, doubt the direction of bad research, and doubt their own ability ... "In bad doubts, they gradually lost their words, lost their concentration and perseverance, and lost their perseverance. What they do is, maybe they miss the success that is only one step away from success. Everyone wants to achieve something. Before we begin, let's look at the "Digging Well Map" and think about whether we are ready: who has prepared enough letters, words and courage, concentration and perseverance.
