Discipline is the self-control that is gained by requiring that rules or orders be obeyed, and the ability to keep working at something that is difficult. Disciplinarians believe that such self-control is of the utmost importance and enforce a set of rules that aim to develop such behavior. Such enforcement is sometimes based on punishment, although there is a clear difference between the two. One way to convey such differences is through the root meaning of each word: discipline means "to teach", while punishment means "to correct or cause pain". Both punishment and discipline aim to correct harmful actions and teach about consequences, instilling responsibility, boundaries, and self-control. They share the goal of modifying behavior to promote respect for rules and others, however Punishment mainly focuses on making someone suffer for past misbehavior through penalties like restrictions or reprimands, while discipline teaches skills for better future choices via guidance and understanding consequences.
