I never fear Mercury retrograde. It has its irritations (I just lost an entire post I was writing with one errant keystroke) but it generally goes really well for me. I was talking about that with Allegra just now. She feels she thinks more clearly during these periods. So do I. I don’t think it has so much to do with having Mercury retrograde natally, although that is one possible reason.
I think the main reason is more general: anything that creates a situation where a person glosses over information the first time it comes around. Perhaps you get overwhelmed with a barrage of constant or simultaneous information flow. Perhaps, like me, you tend to set things aside because you didn’t know what to do with them at first sight. Perhaps you’re a slower processor and the world moves faster than you do. Maybe you get overwhelmed, or maybe you specialize, to the exclusion of some data.
Whatever the case, Mercury retrograde brings these things around again for reprocessing. Whatever it is you personally missed? Here it is! And it’s familiar (particularly good for heavily fixed people).
What could make you a great Mercury retro processor? A SuperRetcher? I’d say anyone with fixed energy associated with their Mercury would appreciate the redirect. It gives one familiarity with the subject and therefore mastery and confidence the second time around.
Neptune attached to your Mercury either by sign (Pisces Mercury) or by aspect can do this; it creates confusion or overwhelm. Another shot, again, brings confidence. Saturn influencing Mercury might also have this effect. Slower processors benefit from another grab at the brass ring. The third house situation also applies here, so do so-called poorly placed/aspected or unaspected Mercuries.
There are many ways this could be true. But it also helps to look at this period from that open perspective. You might be a SuperRetcher (I love using gross names) too and just not know it! If you relax and give it a chance to flow back to you, you might find that you are!
