Self-esteem is a person’s perception of their self-worth and is an important part of succeeding in life and being happy. How we view ourselves affects how we act with others and influences what we believe we can achieve. Teenagers commonly struggle with poor self-esteem because they are still developing a sense of who they are and what they are capable of. Fortunately, as a parent you can help your teenager develop a positive self-image and high self-esteem.
