Have you made some plans/promises lately? Did someone offer you a deal or opportunity? Back the truck up...you're not driving off just yet. Jupiter went retrograde in Gemini today (at 16 degrees), and Mercury (Gemini's ruler) is going to connect with Saturn in Libra, tomorrow morning (just before they both enter Scorpio).
So that exciting idea/bit of intel/invitation has not only hit a wall (Saturn), it's going in reverse. What to do? Jupiter will be retrograde in Gemini until January 30th, 2013. That doesn't mean all Gemini related things (communication, options, information) must be put on hold until then. But it does mean that you'll have to review what Jupiter has brought you, since it entered Gemini on June 11, 2012. And there's probably a good reason...Jupiter's expansive energy can cause you to overlook certain details (Gemini). Or over-promise. Now's the time to double check, and cut back if need be.
Mercury's confrontation with Saturn will just be an initial check point. What's the truth behind his/her charming words? Can you deliver on your promises? Can they? You'll find out tomorrow. If the answer is "Yes", you can move ahead. But things will progress more slowly (because of delays) while Jupiter is retrograde. If the answer is "No"...then drop it, reboot, and go back over existing plans and opportunities. Jupiter retrograde is a second chance. You can make a more appropriate choice, deliver a more thorough evaluation, or say it differently.
If you have planets between 6 and 16 degrees Gemini, Jupiter's retrograde will impact you most strongly. If you have planets between 28-29 degrees Libra, the Mercury/Saturn conjunction will be a major reality check for you.
