Mercury
Mercury governs how a person thinks and communicates. It sets the tempo and texture of the mind, determining whether thought moves in quick associations or slow, deliberate chains. Mercury also shapes the words a person reaches for first and how comfortably silence sits alongside speech.
In Capricorn

How your mind works when it's just you
Your mind works best alone, but it holds itself to impossible standards
When you think something through on your own, something sharpens. The noise drops away, and your mind goes to work with a focus that feels almost physical. You are not someone who thinks out loud easily. You prefer to arrive at conclusions already formed, already tested, already confident enough to say. That preference is not shyness. It is a kind of precision instinct: you would rather be right than fast.
The cost sits inside that same preference. Because you set the bar before you begin, the thinking can stall before it starts. There is a version of rigor that becomes a reason not to begin, not to share, not to let the thought be half-finished in front of anyone. You know when you are holding back something real because it is not polished enough yet. That delay has a toll you do not always name.
What drives this is a deep belief that how you think reflects who you are. Sloppy thinking feels like a personal failure, not just an off day. Your mind became a place you had to earn the right to trust, and so you learned to build slowly, verify carefully, commit only when certain. That is not a wound. It is a standard you set early and have kept.
