One of the hardest things for us to learn is that of Humility. All too often, I have both seen and heard of situations where other people make fun of someone because of their educational level, race, background, economic situation, or social status.
Many people tend to walk around with an "elitist" attitude and feel they are superior to other people. I have found that when a person needs to believe that they are superior or better than someone else, he/she is really suffering from a lack of self-esteem and self-worth in their own life.
I encourage everyone to be more receptive towards others and their situations and not think you are better than someone else.
