Extra than ordinary is Extraordinary.

To be extraordinary, a person should always try to do something extra than other people around him. I think that this can take him to next higher level where the work of his other colleagues would be more than his earlier ones. Now again the challenge is to do extra than these persons. The cycle would continue and the base line would be continuosly going up.
A very famous small story is there on this. Once upon a time, two friends were passing through a jungle. Suddenly they heard a lion's roar behind them. Both understood that lion was coming in their direction. One friend started running. His friend commented "Do you think that you can run faster than lion?". In reply he said "I don't have any need to run faster than lion, i have to run faster than just you."
