It is a great beginning to get a lay of the land of the astrological signs. I know Steve could talk for hours about each one, but this offers really important lessons that go beyond the superficial, stereotypical versions of each sign, into a deeper, more 3D view of each sign.
Revisiting the Sun
I really appreciated Steven going back to the basics of exploring the profound meaning of the sun sign. He is right on in his assessment that we tend to neglect this important astrological archetype, because it is so overvalued by the public at large. It was good for me to remember that "courage" is the touchstone of my Aries sun, and this helped bring into focus much of what's going on in my life right now.
