The North Wind and the Sun

The North Wind and the Sun disputed which was the more powerful, and agreed that he should be declared the victor who could first strip a wayfaring man of his clothes. The North Wind first tried his power, and blew with all his might; but the keener became his blasts, the closer the Traveller wrapped his cloak around him, till at last, resigning all hope of victory, he called upon the Sun to see what he could do. The Sun suddenly shone out with all his warmth. The Traveller no sooner felt his genial rays than he took off one garment after another, and at last, fairly overcome with heat, undressed, and bathed in a stream that lay in his path.

Persuasion is better than Force.
