There were two brothers, only four or five years old. Because their bedroom window was always kept tightly shut, they found the room too dim and felt very envious of the bright sunlight outside. They suggested, "Let's sweep some of the sunlight inside together." So, the two brothers took brooms and dustpans to the balcony to "sweep the sunlight." However, by the time they brought the dustpans back into the room, the sunlight was gone. They tried this many times, but the room remained just as dark. Their mother, busy in the kitchen, saw their strange behavior and asked, "What are you doing?" They replied, "The room is too dark, so we want to sweep the sunlight in." Their mother smiled and said, "As long as you open the window, the sunlight will come in naturally. Why bother sweeping it?"
Secret: Open your heart, and the sunlight of success will dispel the darkness of failure.
有两个四五岁的兄弟，因为卧室的窗户一直紧闭着，觉得屋内太暗，非常羡慕外面的灿烂阳光。于是他们商量说：“我们可以一起把外面的阳光扫一点进来。”于是，兄弟俩拿着扫帚和畚箕走到阳台去“扫阳光”。可等到他们把畚箕搬回房间时，阳光却不见了。就这样反复尝试了许多次，屋内依然没有阳光。正在厨房忙碌的妈妈看到他们奇怪的行为，问道：“你们在做什么呢？”他们回答说：“房间太暗了，我们要把阳光扫进来。”妈妈笑着说：“只要把窗户打开，阳光自然会进来了，何必非要用扫的呢？”
秘诀：敞开心扉，成功的阳光就能驱散失败的阴霾。
