Your thinking style
Your mind weighs things. You look at a question from several sides, compare options and try to find the solution that is fairest to everyone involved. Cardinal air gives you initiative in conversation and in bringing people together. You tend to think best in dialogue, sharpening your ideas by talking them through with someone else.
How you communicate
You speak with tact and charm. Astrologers link Mercury in Libra with a talent for diplomacy, negotiation and saying difficult things gracefully. You usually pay attention to how something is said as well as what is said, and you dislike rudeness. People often come to you when they need a mediator or a second opinion.
How you learn
You learn well with others: study partners, discussion groups and teachers you can talk to. Seeing how ideas relate to each other, and comparing different theories, helps you understand them. You often enjoy subjects that involve people, art, design or justice. An attractive, calm setting can make it easier for you to concentrate.
At work
At work you are good at bringing people together and keeping cooperation smooth. Astrologers link this placement with law, mediation, diplomacy, design, client relations, human resources and any role where fairness and taste matter. You often do your best thinking in partnership. Hostile or chaotic workplaces can wear you down quickly.
In relationships
In close relationships you are considerate, attentive and a good listener. You care about keeping communication friendly and fair, and you will try hard to understand the other person’s position. Romance and conversation often go together for you. A partner or friend who talks openly and treats you as an equal brings out the best in you.
Challenges
Your biggest test is making a decision. Seeing every side can make it hard to choose one, and you may agree in the moment to avoid friction and regret it later. You might also soften a message so much that its point gets lost. Trusting your own judgment, and accepting that a fair answer can still disappoint someone, makes your diplomacy stronger.
Mercury in Libra and your Sun sign
Seen from Earth, Mercury never strays more than about 28 degrees from the Sun, so your Mercury sign is always your Sun sign or one of the two signs next to it. Between 1990 and 2035, Mercury passes through Libra 46 times. A typical passage lasts 20 days and the shortest 17 days. The longest, from Aug 31, 2034 to Nov 7, 2034, adds up to 68 days in Libra, because Mercury turned retrograde in or near the sign. Here is how the Sun signs of people born with Mercury in Libra are spread across that period:
