“Boundaries define us. They define what is me and what is not me. A boundary shows me where i end and someone else begins, leading me to a sense of ownership. Knowing what I am to own and take responsibility for gives me freedom. Taking responsibility for my life opens up many different options. Boundaries help us keep the good in and the bad out. Setting boundaries inevitably involves taking responsibility for your choices. You are the one who makes them. You are the one who must live with their consequences. And you are the one who may be keeping yourself from making the choices you could be happy with. We must own our own thoughts and clarify distorted thinking.”
