a tale of performance

Heard in a performance review meeting.
Two villages, similar in all respects, had a famine. The folks of the first village did a rain dance. It rained. Watching the amazing results, the folks of the second village danced too. But it did not rain. They were puzzled. The Chief of the first village, was asked by the second one, to tell them why it did not rain, as they did a similar rain dance. The Chief solved the mystery.
The folks of the second village, danced for the rain to come, while the first, danced till the rain had come.
It is a matter of perseverance.
