I know its a definition but I dislike the concept of discipline as being punishment. I prefer to think of it as a redirection or correction to bring someone in line with an expectation or standard. But that's just me. I put discipline somewhat in the category of positive reinforcement. As Skinner intended it, it only occurs when a positive or desired change in behavior occurs. Punishment on the other hand does not always have to result in a change in behavior for the good.
