If you push someone too far, they will react to the pushing, not about what you are arguing for. Persuasiveness is more effective than force; gentleness does more than violence.
- The North Wind and the Sun @ Wikipedia
Excerpt: The story concerns a competition between the North wind and the Sun to decide which is the stronger of the two. The challenge was to make a passing traveler remove his cloak. However hard the North Wind blew, the traveler only wrapped his cloak tighter, but when the Sun shone, the traveler was overcome with heat and had to take his cloak off.
