The 12 Bad Habits That Hold Good People Back: Overcoming the Behavior Patterns That Keep You From Getting Ahead
James Waldroop Ph.D. (Author), Timothy Butler Ph.D. (Author)
I mentioned this book at the last meetup, so here is the link:
It is a self-help book that has nothing to do with astrology, but each of the 12 habits is clearly related to a sign of the zodiac. I marked which chapter belonged to which sign in my copy, but I have no idea where it is now. I would not be surprised to find out that the authors secretly based this work on astrology.
