A group of tiny frogs held a race to climb a tall tower, but the crowd doubted any of them could reach the top. One by one, the frogs gave up from exhaustion or discouragement from the crowd shouting they couldn't do it. However, one frog persisted and ultimately reached the top, while all the others had stopped trying. It was then revealed that the winning frog was deaf, so it couldn't hear the crowd's negative and discouraging comments. The lesson is that people's negative words can undermine one's dreams and efforts, so it's best to ignore doubters and stay positive.
