Unity still remains the key to success. I believe competition started from the time of Cain and Abel as were the first record of men who competed. I also think God himself design competition because he rejected the gift of Cain. On a normal human thinking, if Cain was supposed to have the chance to come back to give an offering to God, he will want to give better. On the other hand Abel, who his sacrifice was accepted, will also want to do more better so that his offerings might always be accepted. Competition is within us from ages. The best form of competition is competing against yourself not others... You'll improve more.
