In a calm sea every man is a pilot. But all sunshine without shade, all pleasure without pain, is not life at all. Take the lot of the happiest—it is a tangledyarn（纱线）. Bereavements and blessings, one following anther, make us sad and blessed by turns. Even death itself makes life more loving. Men come closest to their true selves in the sober moments of life, under the shadows of sorrow and loss. In the affairs of life or of business, it is not intellect that tells so much as character, not brains so much as heart, not genius so much as self-control, patience, and discipline, regulated by judgment. I have always believe that the man who has begun to live more seriously within begins to live more simply without. In an age ofextravagance and waste（铺张浪费）, I wish I could show to the world how few the real wants of humanity are. To regret one's errors to the point of not repeating them is truerepentance（悔改）. There is nothing noble in being superior to some other man. The true nobility is in being superior to your previous self.
