One of the characteristics of a person is that they think others are better than themselves, and that they are inferior to others, despise and doubt their own abilities. Everyone is more or less inferiority, but we should not be afraid of low self-esteem, we should surpass the inferiority, and let the inferiority become a good character -- modesty and caution, and turn into the motivation of progress. Only in this way can you live happily and your life will be full of hope.
