Mercury in Aries — your mind is fast, direct, sometimes sharp. You say the first thing that comes to mind, and you are often right — because your intuition works at the pace of lightning. You do not like long reasoning: the point, the fact, the decision. The shadow is impatience with slow thinkers, a tendency to interrupt, anger in an argument. Learn to hear people out sometimes — sometimes another's thought reaches where your lightning does not fly.
Mercury in Taurus — you think slowly but solidly. Your decisions, once made, are grounded like a foundation. You remember theory poorly but remember well what you have tried with your hands. Your voice is usually beautiful, calm, trustworthy. The shadow is stubbornness of thinking, an unwillingness to change your mind even when the facts have changed, a tendency to routine thinking. Learn to review your beliefs sometimes — or they turn into dogmas.
Mercury in Gemini — its home sign, you have an exceptionally lively, curious, multitasking mind. You can hold three conversations at once, read five books in parallel, keep ten ideas in your head. Words are your natural element: you speak, write, tell, explain with ease. The shadow is superficiality, a tendency to jump from topic to topic, an inability for deep concentration, sometimes untruthfulness from the ease with which you change the narrative. Learn to choose one topic and go into its depths — or your whole life will be a collection of interesting but unfinished projects.
Mercury in Cancer — you think not in words but in images and feelings. You do have logic, but it passes through the heart: you cannot separate a thought from an emotion, a fact from a mood. You have an excellent memory, especially for emotionally coloured events. The shadow is subjectivity (you see what you want to see), a tendency to take offence when misunderstood, a defensive reaction instead of arguments. Learn to look at a situation through others' eyes sometimes — your own truth is not the only one.
Mercury in Leo — you speak beautifully, vividly, on a grand scale. Your ideas are always large, your stories captivating, your speeches memorable. It matters to you how you sound, not only what you say. The shadow is a self-assurance that gets in the way of listening, a tendency to exaggerate, hurt when criticised. Learn to listen in silence sometimes — not every conversation has to be a monologue.
Mercury in Virgo — its home sign, you have an analytical, precise, differentiating mind. You notice details, errors, inaccuracies; your language is clean, clear, without extra words. An ideal mind for an editor, analyst, programmer, doctor. The shadow is pickiness, perfectionism in speech (paralysis before publishing), criticism as a form of aggression, an anxiety that will not let you relax. Learn to let go of the standard sometimes — or you will stay silent where you needed to speak.
Mercury in Libra — you think through dialogue and comparison. You need to talk an idea through with someone for it to become clear. You see two sides of every question, and this makes you a wonderful negotiator. The shadow is indecision (you cannot choose one solution, seeing the pros and cons of all), people-pleasing in speech (you say what the listener wants to hear), intellectual insincerity. Learn to speak directly sometimes — even if it breaks the harmony of the moment.
Mercury in Scorpio — you have a deep, penetrating mind, able to see hidden motives and unspoken subtexts. You rarely say everything you think, keeping part in reserve. A wonderful detective, psychologist, explorer of secrets. The shadow is paranoia (you see a double meaning everywhere), manipulative speech, using information as a weapon, silence as punishment. Learn to speak openly and trust sometimes — or only the people you have managed to "see through" will remain around you.
Mercury in Sagittarius — you think in large categories: meanings, ideas, philosophy, perspectives. Details irritate you, the whole picture is native to you. You are a wonderful teacher, preacher, traveller. The shadow is dogmatism (my truth is the only one), carelessness with facts (you often err in details for the sake of a vivid story), moralising. Learn to be precise sometimes — a big idea without precise details turns into propaganda.
Mercury in Capricorn — you think strategically, slowly, reliably. Your decisions are well-grounded, your promises are kept, your plans are realistic. A wonderful mind for business, law, architecture. The shadow is pessimism (you see problems where others see opportunities), a dryness of speech, a fear of error that paralyses creativity. Learn to improvise sometimes — not every decision has to be built ten steps ahead.
Mercury in Aquarius — you think originally, sometimes strangely, always not like everyone else. You have leaps of logic that lead to unexpected discoveries. A wonderful mind for science, technology, invention, unconventional business. The shadow is detachment from living people in favour of abstract ideas, provocation for provocation's sake, contempt for traditional thinking. Learn to think like everyone else sometimes — or your ideas will be brilliant but inaccessible.
Mercury in Pisces — you think not linearly but in images, metaphorically, through sensations. Logic is not the main thing for you; what matters is to feel the essence. A wonderful mind for art, psychology, spiritual practice, poetry. The shadow is absent-mindedness (you lose the thread of a conversation), confusion with facts, a tendency to self-deception, an inability for structured thinking. Learn to be concrete sometimes — or your beautiful intuitions will stay in the fog.
