There was a water carrier whose job was to fill the water jars at a wealthy household. He always used two jars. One was perfectly intact, while the other had a small crack that caused it to leak a bit of water.
Because of the cracked jar, it took him more time to fill the jars. But he never threw it away.
That was because the water that leaked from the cracked jar caused grass and flowers to bloom along the dirt path he walked every day, bringing a smile to his face.
