We all know how difficult it is to exercise self-discipline. This is why when we are raised with discipline it makes it so much easier. Structure and limits become ingrained within us. When we raise our children without structure and limits, when we are a yes parent, we aren't being nice. We are being very, very mean. Why? Our children will suffer greatly from this later in life. As difficult as it is for a parent to implement structure and limits, it's far more difficult to later in life.
