look not mournfully into the past.it comes not back again. wisely improve the present. It is thine. go forth to meet the shadowy future, without fear, and with a manly heart.不要悲伤的沉迷于过去，过去永远不会归来；明智地抓住现在，现在的一切属于您；去迎接虚幻的未来吧，无需害怕，携带一颗勇敢的心灵。

who never his bread in sorrow ate, who never the mournful midnight hours,weeping upon his bed has sate, he knows you not, ye heavenly powers 不要在悲伤的时候吃饭，不要在午夜悲伤的坐在床上哭涕，他知道你没有无上的能力。
