Buddhist tradition asserts the doctrine of anatman, or non-self. This states that "you" don't inherently exist. What you perceive as yourself is simply an impermanent conglomerate of your surrounding conditions at that time.
Anatman is empowering because it means that you are an ever-changing phenomenon that is co-dependent with all other phenomena around you. You exert an impact on others and on everything with which they do in turn. As they do on you and on everything with which you do.
Choice is an active, rather than passive, process. Each formation of "self" plays a role in each successive formation "self," and that is powerful. At each point in time, you control what you choose to do given the preconditions that make "you" at that moment.
Furthermore, anatman is a useful doctrine because it can liberate you from thinking of yourself as a static and corporeal being. Unpleasant feelings, perceptions, and physical embodiments, are all transient. They are specific to that present moment of phenomenological "self."
During each step in life, it is possible to create the preconditions of a positive "self." At every moment, your "self" is contingent on the circumstances that have been created by all the actors in the circumscribed space of your "self"--including "you."
