Boundaries are lines you draw and clarify between yourself and others that maintain your individuality and identity – your definition of who you are, separate from everyone else. Your boundaries are necessary all the time. The need for boundaries is as constant as your need to breathe.
Our boundaries change throughout our lives, as we develop and mature. Our most basic, primitive, and immature boundaries are about protecting and defending ourselves against the “outside world” by controlling other people and/or externals in our lives.
