In modern society, there are also many born disabled people, but some people give up on themselves, don't try to change their own destiny, or beg, or rely on others to survive at home. Who says that people with defects are inferior to others?

We don't deny that disabled people will bring difficulties to people. However, there is a good saying in China that the stupid bird flies first. I believe that as long as I can achieve my own peak through my own efforts, just like a normal person, I must persevere. One's world outlook can be changed, but one's belief should be persistent, and one's firm belief in being kind to others and taking pleasure in helping others should remain unchanged for life, that is, the lure of material desire, the drive of utility and the attraction of pleasure should not be abandoned halfway.

everyone is eager for success. Fighting for success is like running to a distant goal. The road is rugged and long, and there are all kinds of obstacles hidden on the road. Can you resist the lure of material desires, the drive of utility, and the attraction of amusement? Years of hardship, ten years of cold window, and even a lifetime of burying your head, you can bear it.

some people retreat and have to give up halfway; Some people are discouraged and have to give up all their efforts; Some people are exposed to the cold and have to accomplish nothing. Only the persevering people walk with unswerving steps and have no hesitation, and finally bathe in the glory of victory and taste the joy of success.
