Self-esteem refers to how we regard and appreciate ourselves. It's founded on our perceptions and assumptions about ourselves, which might be tough to change at times. It is the belief in oneself, self-respect and undue pride in yourself. Building self-esteem is a process of unlearning and relearning. It is possible that your self-esteem influences whether or not you like and value yourself as a person, if you are capable of making decisions and asserting yourself, and are aware of your strengths and positive qualities.
