A Thoughtful Process of the Word "More"

I have always wonder how would the world be if the word, "more" did not exist. Would we cherish what we have now and believe that its best for us to stay that way? or would we always have human nature and a selfish mentality to control and think that we should all be better than our next door neighbor, or a family from a third world country like Africa. Until what point should we all say that we have enough in our lives? Well, until that point comes, we will struggle to maintain ourselves and our lives. People like you and I do not cherish everything we have. If you believe you cherish each and everything in your life, tell me why do you always try better than someone else, why do you eat more than you need to, why do you utilize every resource that is given to you and exploit it like any other defenseless country. Its hard to tackle a bull when you do not have the strength, but yet you try it either way because you want to prove a point. You want to prove you are better. My high school teacher always told me to try my best to get great grades in school. I was an average student with at 2.5-2.7 GPA. At times i believed she took it to far when she once told be i had more capability than a student called blank. This is not about competition, if our schools encourage us to be selfish and self encouraged by someone else's failure, how would this world turn out to be?
