On Wind and the Sun

I would like to share a story. The sun and the wind got into an argument. How to prove who is better? They saw a man walking with a jacket. They decide that the one who forces the jacket off will be the winner. Fair enough. The wind gives it the first go. It blows, the man clasps. It blows harder, the man clasps harder. This goes on for a while. Finally the wind gives up. It is the sun's turn. It spreads its warmth. The man takes off his jacket.

Morale of the story?..Who can take a leaf from this book?
