A man cann't be defeated by everything but himself.

We must defeat much things to fear in our heart now so as not to fail in difficulties in the future,
We know there's much to fear.but before we know we can ,there can be miracles,isnot it?

第一句：cann't 应该是can't

而且应该是
A man can't be defeated by anything but himself.

everything 换成 anything

第二句：heart 换成 determination 比较好

第三句：不通顺
We must defeat the many things we fear in our heart now so that we do not fail when faced with difficulities in the future.

第四句：看不太懂

总结：句子不通顺，但意思大概猜得出来
