people's potential is linitless.never look down upon anybody

你这题目都有问题,明显该是limitless而不是你这个linitless.下面开始正文：
As the sayings goes,people's potential is limitless,so never look down upon anybody.And I think it is very correct.
There are many examples that can prove the saying in our life.The person with some problems on his body often could do many things we couldn't.For example,Hocking（霍金）,the famour scientist who wrote the ,has something wrong with his body.He even could not move except his fingers,but he was so successful in the field of physics.And most of our normal people even could not understand the theory he invented.
So we should not look down upon anybody,because people's potential is limitless.Meanwhile,we should find our potential and do our best with it to achieve the dream we have.
