if i were a boy again, i would cultivate courage. “nothing is so mild and gentle as courage, nothing so cruel and pitiless as cowardice,” says a wise author. we too often borrow trouble, and anticipate that may never appear.” the fear of ill exceeds the ill we fear.” dangers will arise in any career, but presence of mind will often conquer the worst of them. 对一切祸福做好准备，那么就没有什么灾难可以害怕的了。
