Why is self-esteem at the core of most issues in human relations?

Psychological research has shown that lower self-esteem is related to a variety of mental health problems, including alcoholism, anxiety, and depression-all of which cause problems on the job. Higher self-esteem, on the other hand, improves attitudes, job morale, and overall quality of life. In the workplace, healthy self-esteem is the key to top performance and high-quality work-especially when the work directly affects other people.
