A teacher makes a 1-meter line on the board, then the teacher says: "kids try to shorten this line !!" the first child comes forward he removes 20 cm from the line and the line becomes 80 cm. The teacher invited the 2nd child to come forward, he did the same thing, now the line is only 60 cm. Children 3 and 4 went forward to do the same thing, so the line was 20 cm. Finally, a wise child comes forward. It does not diminish the 20 cm line, but creates a new line of 120 cm long, longer than the first line. The teacher taps him on the shoulder, "you are wise, to make the line short, no need to remove it, just make another longer line, then the first line will be shorter by itself".
The message we can learn from the short story above is, To be the best do not need to drop, get rid of or vilify the other. Just do good better on a consistent and continuous basis. Let time prove our quality. "The gems will still shine even in a deep dark mud.
