Power is not the ability to exert your will upon another person. There is no inner security in that kind of power. That is an attribute of time, and as time changes, that changes, too. That will change. That will change.
Real power is no longer the ability to manipulate or to control what appears to be external.
For example, manipulating someone's opinion because you drive a Jaguar. Or because your dredlocks are this long. Or because of your clothes are very ragged or sharp. You know in yourself if you are using your appearance in order to feel better or more comfortable or more secure in the world. That is trying to reach outward to make yourself feel better inwardly.
