Harriet Lerner said this quote
“ We may view it as our responsibility to control something that is not in fact within our control and yet fail to exercise the power and authority that we do have over our own behavior. Mothers cannot make children think, feel, or be a certain way, but we can be firm, consistent, and clear about what behavior we will and will not tolerate, and what the consequences are for misbehavior. We can also change our part in patterns that keep family members stuck. At the same time we are doomed to failure with any self-help venture if we view the problem as existing within ourselves—or within the child or the child’s father, for that matter. There is never one villain in family life, although it may appear that way on the surface. ”
