Growth needs competition. A few minutes after class, my body began to get tired again. It's only the second week of school, and I feel this way again unconsciously. Because there is no competition during the holiday. I think this is the way to grow up. In the long life, competition is indispensable. There is competition to make progress, that is to say, social progress depends on competition. Every time I walk on my way home, I blow the cool air and enjoy the curved flowers and plants on the roadside. As we all know, they are growing happily in such a rainy and sunny environment. But if you have been to the jungle, you will know how fragile these flowers are. Plants need sunshine, but what if they are blocked by other trees? There is no reason to compete. If you don't want to compare with others, you must be more capable than others. That's why the trees there grow so straight and tall that they can get more sunshine. After talking about the ground, I'm looking underground. If you dig out the soil under a tree, you will find how thick the root of the tree is, even reaching tens of meters underground. If we compare the trunk to human talent and the forest to society, then the higher the trunk, the more sunshine it provides to the roots, and the thicker and deeper the roots are. It can be concluded from this that people need to compete.
