帮我看看这篇英语文章

MY Hero
My hero is John Nash,an outstanding mathematician. He is now a professor in Princeton University,who is famous for the great theory — game theory. (此段应简化）
He is a genius and he has great potential in math（这句and前后的意思很相近应去掉and前的部分） He once studied in Princeton University for his doctor’s degree. Then He won the Nobel Prize in 1994.
But this is not the most important thing. John got a serious disease—schizophrenia. Although he suffered both the mental and physical pain, he didn’t give up his career. He regarded his research as all he has. During this hard period, Nash devoted himself to the math research. As a reslut(用这个更好），he succeeded.
What I learned from him is the courage to face life, never stop study and always try to find the mysteries of the world.
And by the way, my dream is to be a mathematician like John Nash. It is not a big dream that I can’t achieve.(这里用强调句很能表达你的信心） I always believe that if I can dream it, then I can make it, successfully！
希望能帮到你~

mathematician. And he is 建议连为一句，即mathematician and he is

as all he has 建议改为过去式 ，as all he had
W
hat I learned from him 建议改为完成时，What I has learned from him

the courage to face life, never stop study and always try to find the mysteries of the world.个人觉得整句话都有问题，动词原形是不可以直接做句子主语的，stop 和try 不可以直接用原形在这里作主语。这样改行不？-->
we all should keep studying hard and always trying to seek the mysteries of the world.

But don’t think 建议改成 However,don't think
我觉得在语法上就没有太大问题了，可是在语句衔接上可以再适当地添加关联词，这样会使文章更流畅通顺。
我也不是很专业的啦，不过还是希望以上的对你有帮助。
