Einstein, a famous scientist, was suspected as an "imbecile" by his family when he was a child. After school, he is still very slow, slow and stupid, and his grades are extremely poor. He is a standard clumsy person. Therefore, some people regard him as a typical example of "diligence can make up for mistakes" and say that his achievements are entirely due to diligence. In fact, Einstein's strong curiosity and tenacious spirit of exploration made him have the courage to break through the shackles of the old theoretical framework of physics, made essential changes to the basic concepts of space and time, and opened up a new era of physics. Relativity is by no means the product of hard work.

For generations of farmers, there is no "work at sunrise, rest at sunset", and the loess with their backs to the sky can be said to be "not diligent", but in the end, they have little harvest, and at most they can produce a few hundred kilograms of grain per mu. The result of "hard work" is that it is difficult for you to eat and wear warm clothes. Yuan Longping, the father of hybrid rice in the world, created the world record of "super rice" with yield per mu1137kg.

"Diligence is the foundation, and enlightenment is the first". Diligence and hard work are the basic conditions for good grades in study and great achievements in career, and the key to success is to recognize the laws of learning, the nature of things and scientific methods. "Diligence" is only the "+"sign in the formula of success, and more work pays more; "Enlightenment" is the "X" in the formula of success, and mastering scientific methods may get twice the result with half the effort.

Diligence is better than laziness in making up for mistakes, but it is difficult to achieve results by relying solely on diligence. Therefore, our conclusion is that diligence is hard to make up.
