Asserting your boundaries can be a frightening and scary prospect, especially for those of us who have never done so before. We may be afraid of conflict, or terrified at the possibility of being disliked by others who might not agree with our boundaries. Despite the initial reluctance, it is nevertheless crucial for us to express and communicate with others things that are not acceptable to us. This helps us to develop a positive self-esteem and attract healthy relationships in our lives.
