I didn't mention self-knowledge, it is another kind of information I was referring to. It is obvious to me too, that knowledge of self is not enough. Something new is needed if old patterns of behavior are to be stopped and new patterns of behavior are to be made.
I am speaking to Awuh1's point that we are all powerless, that power is needed. I compared power to knowledge, not knowledge of self, but other kinds of knowledge, and suggested that some need more power, others need more knowledge, and the suitability of either direction depends on the individual's locus of control - internal needs more information, external needs more power, and both necessarily come from outside the individual.
