What Are Boundaries?
Boundaries are guidelines, rules or limits that a person creates to identify for themselves what are reasonable, safe and permissible ways for other people to behave around them and how they will respond when someone steps outside those limits.
The easiest way to think about a boundary is a property line. We have all seen “No Trespassing” signs, which send a clear message that if you violate that boundary, there will be a consequence. This type of boundary is easy to picture and understand because you can see the sign and the border it protects. Personal boundaries can be harder to define because the lines are invisible, can change, and are unique to each individual.
Creating healthy boundaries is empowering. By recognising the need to set and enforce limits, you protect your self-esteem, maintain self-respect, and enjoy healthy relationships.
