The fable of the sun and the wind, by Aesop.

As winter was about to clear for spring, the Sun and the Wind had an argument of who was the stronger of the two.

Spotting a lone wanderer struggling over a ragged mountainside, the Sun and the Wind decided that the strongest of them should be able to wrest the coat from the stranger's back.

As the Wind started to blow and tear in the wanderer's clothing, the wanderer pulled his coat even tighter over himself and found a crevice where he could shield himself from its reach. This is impossible said the Wind. He's just too stubborn.

When the Wind had finished, the Sun gently dispersed the clouds and started to radiate. As the wanderer had left his hiding place and was carrying on over the mountain, he smiled up toward the sun and nonchalantly threw his coat over his shoulder.
