In ancient Greek mythology we learn about a young man named Narcissus. He was so beautiful that he fell in love with his own reflection  . He became obsessed  , but soon realized that what he loved was not real. As a result, he became sad and died. In the place where he had stood appeared a soft yellow flower -a narcissus.

The other reason that narcissism is considered an ugly thing is because we are taught that we should care more about others than ourselves and that it's better to give than to receive.  Thinking about others is the right thing to do, without question. But psychologists say that the love of others is actually based on self-love. If you see yourself as an unpleasant stranger, how can you be capable of making friends with anyone else? After all, you are closer to yourself than anyone else. After years of study, scientists also found that parents play a big part in building a child's self-belief. Only if the parents approve and accept their children, do they feel loved and learn to love themselves. The next time you look in the mirror, try to tell yourself that you are one of a kind. Pick out your best qualities and be proud of yourself. According to the text, low self-esteem   _  .
