When a person has his natal Mercury in Aries, the sign will grant a big part of its attributes to everything that Mercury represents in his chart. As Mercury is generally governing our intellect and communication, Aries energy will make the native’s expression quite fiery and dynamic. Aries is the first sign of the zodiac, and has the planet Mars as its ruling celestial body. Aries is also the natural ruler of the first house, which rules our ego. This will make Aries Mercury people promote their ego through their speech, and sometimes even force themselves and their ideas on others. The hot temperaments of Mars make the mind function quickly or even hastily.
Mercury in Aries tends to influence determined, agile, and competitive reasoning. The natives tend to have a greater appreciation, as I argue, it is probably what is not lacking. Since they usually have the ability to think quickly, fighting verbal battles with whoever has this position, winning can be more difficult. This agile mind also brings many original ideas to the person. The problem is that it can also make them think that they are intellectually superior, smarter and wiser than others.
This is a Mercury position that can cause people with that position to make hasty decisions, as they do not like to wait. Anything that takes time can make them more impatient. As they tend to have a very personal point of view about everything, they don’t really like to go through long or frustrating processes to figure things out – the thing is to act and make a decision right away, as they feel like they know exactly what is going on! must do!
However, their impulsiveness means that they don’t always finish the ideas they start, unless another sign or aspect in their charts somewhat tempers this tendency.
As knowledge is gained rapidly, in a wave of rapid assimilation as if a whole situation were being built in the mind immediately, it may be necessary to lessen anxiety about acquiring this new knowledge or states of consciousness, as it may there can be impatience as long as the circumstances are not related to speed or the use of all this eagerness.
