Aside from how others see them, people have their own ideas about their sense of social identity and status. Some may be self-confident with a high level of self-esteem. However, if this becomes exaggerated it may lead to the development of an anti-social trait such as arrogance or snobbishness. On the other hand, those that lack self-esteem may be filled with self-doubt. Some people may continually feel the need to impress in order to maintain or build a positive self-image.
