Slow and steady wins the race

The Tortoise and the Hare is a fable attributed to Aesop. French poet Jean de La Fontaine adapted into the poem: "le lièvre et la tortu". The story concerns a hare who one day ridiculed a slow-moving tortoise. In response, the tortoise challenged his swift mocker to a race.
The hare soon left the tortoise far behind and, confident of winning, he decided to take a nap midway through the course. When he awoke, however, he found that his competitor, crawling slowly but steadily, had already won the race (although in some versions, he may have also been bragging to some other people).
He sat under the tree and soon fell asleep. The tortoise, plodding on, overtook him and finished the race. The hare woke up and realized that he had lost the race.
The moral, stated at the end of the fable, is, "Slow and steady wins the race."
