Self Disciple

This year my Son has started preschool. They send a newsletter home every week. The purpose of the newsletter is to let us parents know what supplies is needed, and what my child is learning in class. We are in our third week of school, and I received a new newsletter today. What is my child is learning this week? The letter M, Colors, and SELF DISCIPLINE! Self Disciple for a 4 year old is hard. Its hard for a 23 year old. Self Disciple towards food has been a BIG struggle for me lately. I have to tell myself that cupcake is not going to help u fit into those jeans.Self Discipline in preschool is necessary no doubt. However, my question is "why is it so hard for people to learn this lesson?"
