This part in particular seems to point out an element worth paying attention to:
From your quote:
( So when uncovering your "personal myth or story," consider what archetypal themes have emerged for you during the course of your lifetime, because each will have shaped where you find yourself in the here-and-now as well as offering clues as to where you might head next. As Jung said, "Anything psychic is Janus-faced: it looks both backwards and forwards. Because it is evolving, it is also preparing the future." )
( Cindy in reference to my last post check this out although I pretty sure you have already viewed this particular video at some point in your past. )
After spending the better part of several hours researching " Jung and Janus-face " on the web I came across this wonderful video interview of Carl Jung from 1959 and at the 28 minute mark Jung almost word for word references some of this same idea you mention above even including his own psychological types including thinking, intuition, and feeling; ( although maybe stating them somewhat a little differently ); and says this psychological point of view " changes " ( or " evolves " if you will; and " is not static " ); through the different life stages. And even though he does not specifically say the term " Janus-face " it seems to me from what you were saying this is indeed what he is talking about. ( Even though this interview covered a wide range of topics that 60 second portion was really illuminating to hear right from the horses mouth. This was very cool! )

I know you have been busy and haven't had a chance to post much; but I thought this was so interesting to come across that I wanted to put it up for you to have a look at when you get to it.
Cheers
