When we think back to our childhood, the method of teaching discipline was completely different. Those of us who grew up before 2000 know that a large part of our parents' discipline was caning, strict discipline, and harsh punishment. Even if we made a small mistake, there was a scolding, and beatings were also used. Our teaching method was direct—if we made a mistake, we would be punished immediately. As a result of this method, we learned a lot, and that discipline remains with us even today. Because, the mistakes for which we were punished in childhood, we did not make them again when we grew up.
