The moral of the story is that slow and steady wins the race.
This is the version of the story that we've all grown up with.

The hare was disappointed at losing the race and he did some soul-searching. He realized that he'd lost the race only because he had been overconfident, careless and lax. If he had not taken things for granted, there's no way the tortoise could have beaten him.

The moral of the story?

Fast and consistent will always beat the slow and steady. If you have two people in your organization, one slow, methodical and reliable, and the other fast and still reliable at what he does, the fast and reliable chap will consistently climb the organizational ladder faster than the slow, methodical chap.

It's good to be slow and steady; but it's better to be fast and reliable.

The tortoise did some thinking this time, and realized that there's no way he can beat the hare in a race the way it was currently formatted.

They started off. In keeping with his self-made commitment to be consistently fast, the hare took off and ran at top speed until he came to a broad river. The finishing line was a couple of kilometers on the other side of the river.
The hare sat there wondering what to do. In the meantime the tortoise trundled along, got into the river, swam to the opposite bank, continued walking and finished the race.
