“Boundaries are a source of liberation. This truth is demonstrated elegantly by the story of a school located next to a busy road. At first the children played only on a small swath of the playground, close to the building where the grown-ups could keep their eyes on them. But then someone constructed a fence around the playground. Now the children were able to play anywhere and everywhere on the playground. Their freedom, in effect, more than doubled. Similarly, when we don’t set clear boundaries in our lives we can end up imprisoned by the limits others have set for us. When we have clear boundaries, on the other hand, we are free to select from the whole area—or the whole range of options—that we have deliberately chosen to explore.”
