8.18.EMF 温故而知新

8-18 EMF Watch a baby learning to walk. When she first goes from crawling to walking, she's down more than she's up. 看看婴儿学习如何走路吧。刚开始从爬行到步行的阶段，她跌倒的次数一定大于她站立的次数。   There may be a few tears, but she quickly bounces back up, ready to try again. The urge to walk, to explore the world in a new way, keeps her going. 也许会掉几滴眼泪，但是她很快就会重振旗鼓，准备再次尝试。对于走路的渴望，想要用全新的方式探索世界的渴望，让她坚持下去。   As adults, we sometimes let our failures discourage us. If something goes wrong one time, we think it will always go wrong. We don't get up and take the next step. 但是我们成年人，有时候会放任自己受失败打击。一旦某些事出错了一回，我们就会觉得永远不会变好。我们不会再站起来，迈出下一步。
