These squares create friction, intellectually, through all types of communication. They also create friction with siblings and neighbors. Look to the houses and signs to understand where the intellectual abilities aren't being developed to their fullest. Mercury and Venus can only form a conjunction and a sextile because they are never 47 degrees away from each other.
Mercury Square Mars. Your sharp tongue often borders on outright rudeness. It tends to alienate the very people whose support you need. Your mind is equally sharp but as undisciplined as your way of speaking. Take time to gather the facts and plan what you're going to say before you say it. After all, being argumentative doesn't get you very far.
Mercury Square Jupiter. You would make a terrific fiction writer or tribal storyteller. Your mind is rich and imaginative, but your judgment is often flawed because you either misinterpret or don't have all the facts. The best way to overcome the challenges of this aspect is through education, books, and any kind of mental training.
Mercury Square Saturn. You're a thinker with a profound mind able to grasp complex issues. But you think and worry too much, dwelling on past injustices and injuries. This may create negative and prejudicial attitudes that ultimately hold you back. You're not always selfish, but the tendency exists. If it's perpetuated, you may become one of those people who believe the end justifies the means.
In order to overcome the challenge of this Mercury Square Saturn, you need to break with your habitual patterns. In other words, you must release the past. Forgive people who have injured you. Strive to consider other people's feelings before you act. This will make your life so much better.
Mercury Square Uranus. Mentally, you're way ahead of the pack. Your insight can be brilliant and original. Your entire thought process is radical and independent but sometimes so unfocused that your energy ends up scattered and wasted. At times you can be so obstinate about your opinions that it borders on intellectual conceit. You can be tactless, which alienates others. You're always in a hurry to get things done. To overcome this challenge, slow down, think before you act and speak, and try to see things the way the other guy does. Don't jump to conclusions.
Mercury Square Neptune. This aspect favors fiction writing, particularly of the mystical variety. It also gives insight into the motives and behaviors of other people, which is helpful in creating interesting fictional characters. Writing or art are constructive ways to channel the challenges of this square, which lends itself to confused thinking and unreliability. Psychic talent is usually evident with this aspect, but it needs to be developed and funneled constructively.
Mercury Square Pluto. You're able to assess a given situation swiftly and accurately. No one puts anything over on you. You're secretive, but when you've got something to say, you don't mince words. Your willpower is well developed, and you may try to force your ideas on others. You don't take anything anyone says at face value; you need to prove the truth to yourself. To conquer this aspect, you need to be less suspicious of others, to speak your mind more gently, and to turn your willpower toward improving yourself.
Mercury Square Nodes. Think before you speak. Otherwise, you may speak at the wrong time and will be sorely misunderstood. Take a deeper interest in the world you inhabit; an awareness of current trends improves your professional ambitions.
Mercury Square Ascendant. It's difficult for you to express yourself. It's not that you lack talent or don't know what you want to say — it's the way you go about it. You benefit from training in speech and writing, through education, workshops, and anything that provides a structure. This, in turn, improves your relationships with the people in your life.
Mercury Square Midheaven. Your communications skills are flawed, and this creates disharmony at home and on the job. The misunderstandings that result make you miserable. Seek educational training in these areas. Apply your natural talent. The change in your life may shock you.
