Our self-perception determines our behavior. If we think we're small, limited, inadequate creatures, then we tend to behave that way, and the energy we radiate reflects those thoughts no matter what we do. If we think we're magnificent creatures with an infinite abundance of love and power to give, then we tend to behave that way. Once again, the energy around us reflects our state of awareness.
