One famous fable by Aesop tells about a thirsty crow that flew all over the fields to look for water. When the crow finally chanced upon a jug of water, it was unable to drink from it because the jug’s neck was too narrow and too heavy for the crow to push down. The crow was about to give up when it was suddenly hit by a good idea. It started picking up pebbles, dropping each into the jug. As more and more pebbles filled the jug, the water level kept rising. Soon it was high enough for the crow to drink. The plan worked!
