Why is self esteem important?
Self-esteem is important because it heavily influences people's choices and decisions. In other words, self-esteem serves a motivational function by making it more or less likely that people will take care of themselves and explore their full potential. People with high self-esteem are also people who are motivated to take care of themselves and to persistently strive towards the fulfillment of personal goals and aspirations. People with lower self-esteem don't tend to regard themselves as worthy of happy outcomes or capable of achieving them and so tend to let important things slide and to be less persistent and resilient in terms of overcoming adversity. They may have the same kinds of goals as people with higher self-esteem, but they are generally less motivated to pursue them to their conclusion.
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.
