We tend to go through life evaluating ourselves and others according to a scale of worth. The idea of self-esteem is the amount of value that we consider we are worth. These values vary from person to person. While we might rate ourselves as being of little value, others might rate us much higher. If we get into the habit of thinking negatively about ourselves, then low self-esteem, or placing little value on ourselves, is the result.
Low self-esteem can be a result of negative life experiences, particularly when we're young and most vulnerable. These experiences may include being criticized or judged negatively, such as by a parent or school bullies. As adults, abusive relationships and very stressful life events can also cause low self-esteem.
Low self-esteem can stay low because of our own self-critical thoughts, which can be triggered by criticism or perceived criticism (even if none is intended, we believe we are being criticized).
