A self-confident person understands that, regardless of the circumstances, the successes and failures of another person will have little effect on their own status or well-being. Therefore, he has very little focus on how the other person lives, whether positive or negative in their life. Conversely, for a person with low self-esteem, a more successful person is a threat to their sense of self, and watching this person fall can be a source of joy and comfort because they feel an improvement in their internal state or position in the group.
