Mediocrity has become our standard! Do we care?

The dictionary defines “Mediocrity” as something ordinary, par for the course or inferior in quality to something else. But then isn’t mediocrity a word created only by humanity? When we are taught at school during our early years, we are taught about excellence and failure. There is no middle ground for words like “Decent”, “Ok”, “Fine” etc. But then when we humans grow up, mediocrity percolates every part of our lives. Though what is considered as mediocre by some, would be considered as excellence by others.
