Self-esteem is a process that begins in infancy and continues throughout a person's life. When children have low self-esteem, they feel bad about themselves, they fail to live up to their potential in school and at home, and they're more likely to engage in high-risk behaviors like sex, drugs and alcohol when they reach adolescence. On the other hand, when children have high self-esteem, they're more likely to be cooperative, respectful and responsible, to avoid high-risk situations, to be self-reliant and to resist negative peer pressure
