Mercury is the planet of intelligence, and when located in the first house of the native, it will create a very communicative character. They have a very quick-thinking mind, are very talkative and enjoy writing, reading and anything that contains information and speech. Expressing themselves is the most important thing in their lives, and their natural curiosity can lead them to amass huge amounts of information in their minds. Their life is all about learning; they won’t stop until their very last day.
People with Mercury located in the house of self, like riddles, puzzles and everything that keeps their mind alert. They often are interested in uncovering mysteries of the world and life. This can draw them either into studying science, or into studying the supernatural. If Mercury is somehow connected to the 6th or the 10th house, the individual might follow a scientific occupation, while if it is connected to some planets located in the 9th house, there are possibilities of an academic work, teaching or publishing. Their mind is processing data quicker than the average person, and they have a faster tempo of learning.
Mercury placed near the Ascendant usually gives a short and quick body, small eyes and an expressive face. If Mercury is adversely aspected, there might exist speech problems such as dyslexia. What they think and what they express determine their self-existence. This makes them pay a lot of attention to how other people express themselves, making them hyper-analytical. This can often annoy other people, as they will constantly feel being observed and judged by the first house Mercury person. Another tendency that natives with Mercury in the 1st house have is speaking a lot, asking a lot and an inability to keep secrets. When Mercury turns retrograde, their speech can become clumsy, bringing them trouble through misunderstandings and other types of miscommunication. As children, they tend to be hyper-energetic, while also capable of doing two or more things at the same time. Just sitting still and relaxing is not an option for them; their mind craves for something interesting to kill boredom. If Mercury is connected to Jupiter with a positive aspect, they can become great comedians. If it is connected with Pluto, they have great discovery abilities; this placement is prominent in detectives and researchers of any kind.
A problematic behavior that can appear to natives with Mercury in the 1st house is not allowing others to express themselves. Indeed, such kind of people can talk for hours, forgetting that people around them have equal rights in expression. This is not done on purpose; the native just forgets to stop talking. Being at the center of attention is a rather sweet position, but it is also good to listen to other people once in a while. Debates might be very appealing for such kind of individuals; nevertheless, they should be fair as they have the tendency to defend their views even when they know they are wrong, just so that they feel victorious.
When Mercury in the 1st house has some tough aspects with Mars, natives have a mischievous nature. Their highly intelligent and alert brain is used as a tool for swindling or even stealing. They understand that the speed of their thoughts is something difficult for others to follow, and they usually are three steps ahead in their thinking, making their insincere strategies frequently succeed. These kinds of tactics are of course destroying their karma and should be avoided. Some transits of slow-moving “malefics” might rebalance the negative karma attracted to Mercury, and usually, the lesson to be learned is not a pleasant one. Instead, such wonderful minds as theirs should be used for the enlightenment of the humanity.
