The importance of boundaries

Boundaries are essential in maintaining personal and social well-being. They define our space, protect our privacy, and help us to maintain healthy relationships with others. When boundaries are not clearly delineated, we may find ourselves constantly being pushed and pulled, leading to feelings of stress and anxiety. Conversely, when boundaries are respected and followed, we can feel more secure and in control of our lives. Therefore, it is important to carefully delineate our boundaries and communicate them clearly to others, so that we can maintain healthy relationships and avoid unnecessary conflicts.
