The tortoise and the hare argued over which was the swifter. So, as a result, they agreed a fixed period of time and a place and parted company. Now the hare, trusting in his natural speed, didn't hurry to set out. He lay down at the side of the road and fell asleep. But the tortoise, well aware of his slowness, didn't stop running and, overtaking the sleeping hare, he arrived first and won the contest.
This fable shows that hard work often prevails over natural talents if they are neglected.
