A successful relationship is composed of two individuals each with a clearly defined sense of her or his own identity. Without our own understanding of self, of whom we are and what makes us unique, it is difficult to engage in the process of an ongoing relationship in a way that functions smoothly and enhances each individual. We need a sense of self in order to clearly communicate our needs, and desires to others. When we have a good sense of our own identity we can appreciate and love those qualities in others that make them a unique person.
 
One feature of a healthy sense of self is the way we understand and work with boundaries. Personal boundaries are the limits we set in relationships that allow us to protect ourselves. Boundaries come from have a good sense of our own self-worth. They make it possible for us to separate our own thoughts and feelings from those of others and to take responsibility for what we think, feel and do.

Boundaries are flexible - they allow us to get close to others when it is appropriate and to maintain our distance when we might be harmed by getting too close. Good boundaries protect us from hurt and pave the way to achieving true intimacy.

In sum, they help us take care of ourselves.
