Self-esteem is defined as one's judgment of their own worthiness and capabilities. It is shaped by life experiences and relationships. People with high self-esteem like meeting new people, are not worried about judgment, and feel they can achieve their goals, while those with low self-esteem do not believe in themselves and feel incapable. Common signs of low self-esteem include exaggerated bragging, blaming others, and being overly reactive. Though self-esteem is formed over time, it can be improved by forgiving mistakes, focusing on strengths, and setting and achieving goals.
