self-esteem is used to describe a person's overall sense of self-worth or personal value. In other words, how much you appreciate and like yourself. It involves a variety of beliefs about yourself, such as the appraisal of your own appearance, beliefs, emotions, and behaviors. Self-esteem can play a significant role in your motivation and success throughout your life. Low self-esteem may hold you back from succeeding at school or work because you don't believe yourself to be capable of success.
By contrast, having a healthy self-esteem can help you achieve because you navigate life with a positive, assertive attitude and believe you can accomplish your goals.
