常听到同窗感慨英雄无用武之地,千里马常有而伯乐不常有。发此类感慨的仁兄,总认为自己四周都是铜墙铁壁,束缚了自己,使别人不能发现自己,也使自己无用武之地。是吗?不是。我认为这“铜墙铁壁”不是社会、别人造成的,而是自己造成的。既然认为自己无用武之地,为什么不破墙为门, It is often heard that there is no use for the heroes of their classmates. There are often thousands of horses and Bole. The kind-hearted dear friend always believes that he is surrounded by walls of iron and steel, and he has bound himself so that no one can discover himself or make him useless. Isn’t it? I think this “iron wall” is not caused by society and others, but is caused by oneself. Since you think you are useless, why not break the wall?
