The Best

What does being the best even mean anymore? Every country says that they are the best. How can all of us be the best? Shouldn't there just be one since it is being the "best:"? We can thank the media for this misconception because no matter where you are the media will always say that they are the best. It is scattered all over from the internet, the paper, even the word of mouth. There is being the best in the Olympics, scientifically, medically, psychologically, artistically, and many other ways that many people don't think about. But to be the best wouldn't you have to be the best in every single field imaginable and no one could do that because there are too many to even think about. So why say that a country is the best when they clearly cannot be?
