【简答题】
In one way of thinking, failure is a part of life. In another way, failure may be a way towards success. The often told “ spider story ” is about Robert Bruce, a leader of the Scots (苏格兰人) in the 13th century, who was hiding himself in a cave from the English. He watched a spider making a net. The spider tried to reach across a place which was very difficult to get to in the rock. He tried six times without success. On the seventh time he made it and went on to make his net. Bruce is said to have taken heart and to have gone on to defeat the English army. Edison, the inventor of the light bulb(电灯泡., made hundreds of models that failed before he found the right way to make one. So what? First, always think about your failure. What caused it? Were conditions right? What can you change so things go right next time? Second, is the goal you are trying to reach the right one? Try to do some thinking about what your goals may be. Think about this question. “ If I do succeed in this, where will it get me?” this may help you prevent failure in things you shouldn’t be doing anyway. The third thing to remember is that failure is a part of life. Learn to “ live with yourself” even though you may have failed.
