Explanation:
A sense of positive regard for oneself, resulting in elevated levels of self-respect, is called self-esteem.
Self-esteem is the way you feel about yourself. People with strong self-esteem are proud of who they are and their accomplishments. While everyone experiences moments of insecurity, those who have poor self-esteem experience these feelings more frequently. This can be fixed, but boosting self-esteem requires focus and regular practise.
Confidence in one's own abilities or worth is referred to as self-esteem. Beliefs and emotional emotions about oneself are also included in self-esteem. People with high self-esteem are proud of who they are and are more likely to succeed in their life.
