Who is best known for saying "I AM THE GREATEST"? He was an American athlete and sports celebrity. Not gonna help you out. Google the expression. When you are taught by other people to be aim at being second best, ask yourself this question. Why do I believe this? Think about the game of bows and arrows. The target is clearly marked. The goal is to hit the bull's eye in order to win. Ignore everything ever written about being No. One (beating competitors) and all psychological studies ever written and published for general consumption if being second best makes you happy. Why would you want to teach somebody else to be second best when being being FIRST or number one brings the greatest amount of happiness? Horse races. Marathon races. Every show on TV that brings people together to win big money. Human beings everywhere compete to win, not aim for second place. Who trains for the Olympic games to win second place? Thanks for listening.
