I remember the story of the Balloon seller in the beach. When ever there is a slump in the sales the balloon seller would fill one balloon with oxygen and release it. When the balloon goes up to the sky, children who are playing around would see the balloon and the sales would go up. One day as usual, he released a balloon. Seeing that one child come to him and asked this question "If you release a Black balloon, will it go up?" The balloon seller replied to that little boy, "The colour of the balloon doesn't make any difference, what is inside the balloon is the matter and it is taking it up."
What is inside the men are taking them up and make them successful. It doesn't matter in which field they work or what kind of business they do or which place they live. Our attitude must be set right.
