As a Confidence Coach, I believe setting personal boundaries is a way of protecting and taking care of yourself, your heart and not allowing this get twisted by people comments, thoughts or feelings about you. It is important to be able to tell people when they are acting in ways that are not acceptable to you and to be able to know that you have the right and duty to protect and defend yourself. It is your responsibility to be clear on how you want others to treat you.
I coach my clients to you learn how to state your feelings verbally and let people know how they feel in a way that communicates clearly. By stating your feelings verbally you affirm your right to your feelings and you know that you are not your feelings you have feelings and they can change from situation to situation, moment to moment. By affirming your feelings it allows you to  take responsibility for yourself and your life. Owning yourself, your reality and your voice is empowering. The result of self-ownership, allows other people to hear and understand you clearly.
Some people might say that setting and having boundaries is not a more sophisticated way of manipulation. So they are set boundaries when in fact they are attempting to manipulate people and situations. The difference between setting boundaries and manipulation is that boundaries are healthy,give people choices and allows you the freedom to let go of the outcome. Whereby, manipulation is not a clear form of communication and it exploits people into doing what you want them to do, by using methods that cause confusion. This confusion has you

create outcomes that only the manipulator is clear about.It is unhealthy to have relationships with people who have no boundaries, who cannot communicate directly, honestly and freely. Learning how to set boundaries is important and necessary for you to be a friend to yourself and others. It is your responsibility to take care and to protect yourself. It is important to love, honor and respect yourself. You cannot truly love yourself if you do not take responsibility. Loving yourself allows you the opportunity and freedom to be a creator in your life. How well do you set boundaries?
