What is the definition of "self-esteem"?

The definition of self-esteem is indeed the subjective evaluation of one's own worth. This concept revolves around how individuals perceive themselves and their value, which is inherently personal and varies from one person to another. Self-esteem encompasses feelings of self-acceptance and self-respect, influencing a person's confidence and overall mental health. This subjective nature means that self-esteem can be shaped by personal experiences, beliefs, and reflections, rather than objective criteria or external assessments.

The other definitions presented do not fully encapsulate the essence of self-esteem. While a belief in one's ability to achieve goals relates to self-efficacy, which is distinct from self-esteem, the objective measurement of personal worth implies an external standard that doesn't align with the inherently personal aspect of self-esteem. Similarly, an assessment based solely on social feedback overlooks the internal processes involved in self-evaluation and the personal perceptions that shape how one feels about themselves. Thus, the correct choice highlights the core principle that self-esteem is fundamentally about individual perceptions and evaluations of personal worth.
