Self-esteem is a term used in
psychology to reflect a
person's overall evaluation or appraisal of his or her own worth.
Self-esteem encompasses beliefs (for example, "I am competent/incompetent") and emotions (for example, triumph/despair, pride/shame). Behavior may reflect self-esteem (for example, assertiveness/shyness, confidence/caution).
Psychologists usually regard self-esteem as an enduring personality characteristic (trait self-esteem), though normal, short-term variations (state self-esteem) occur.
Self-esteem can apply specifically to a particular dimension (for example, "I believe I am a good writer, and feel proud of that in particular") or have global extent (for example, "I believe I am a good person, and feel proud of myself in general").
