Confidence and self-esteem are particularly important during the teenage years. Self-esteem allows teens to feel good about who they are, capable, and worthy of love. Numerous studies have shown just how important self-esteem is for adolescents. Teenagers with high self-esteem are happier, calmer, and more likely to bounce back from failure. Teens with low self-esteem are at increased risk for poor mental health, poverty, and even drug use.
