Because you NEED to know (from astrology.com):
Saturn is often considered the taskmaster planet. And when it goes retrograde? Well, there're no two ways about it: Issues of authority come to the fore, and a conservative attitude toward responsibilities creeps into even the most free-spirited souls. Whether consciously or not, you will probably experience the effects of Saturn's retrograde -- which will last until April 19, 2007 -- as a time to reflect on past decisions and learn from your mistakes ... and definitely not a time to charge easily toward your goals.
That said, Saturn's energy, which rules issues of control and organization, lends itself well to making sound judgment calls as well as wise investments, if both sense and sensibility are properly utilized.
Saturn turning retrograde puts a challenging spin on achieving success, but the planet also rules issues of leadership, making this the ideal time to establish your own boundaries, strive for self-improvement and unleash your creativity on the world. Furthermore, when your goals have been met, you'll be that much more satisfied at having cleared this astrological stumbling block! On the way, you'll also have learned a lot about yourself and clarified your perspective.
