It is one thing to know what your boundaries are. It’s important to know what your boundaries are. But setting healthy boundaries doesn’t start with that. You can know every boundary you want, and if you don’t have this one thing, having healthy ones will be difficult.
The one thing needed to have healthy boundaries in your relationships is self worth. Self-worth is different from self-esteem. It is about knowing your value, for yourself as well as in relationships you have.
It is very difficult to request that someone keep a boundary if you don’t see yourself as priceless. Worthy. Often, we place others value above ours. Somehow they become first.
