Ascendant in Aries:
This position does not make a person aggressive. Forthright, yes, but aggression is too strong a word for these natives. They have a youthful, direct manner that sees what it wants and generally goes for it. At the same time, there isn’t any malice in their intent.
Some Aries rising people are competitive, but they generally put most of the pressure on themselves. These people love to come out ahead in all that they do. They get ready quickly, walk quickly, and have little patience for dilly-dallying. Their temper is quick, too. It’s also quick to disappear. Rarely do you find Aries rising people holding grudges. Their mannerisms are rather simple and straightforward.
Aries rising loves action, and is often trying to stir up some activity. Their strengths lie in their enterprising ways. Finishing things they start does not always come as easily, unless the ruler, Mars, is placed in a more tenacious sign, such as Taurus or Scorpio.
Aries Ascendant often gives a rather swift walk, with the head leaning forward slightly. This walk is surprisingly distinctive. Headaches, and sinus and eye problems are the usual physical complaints of this position. Rashes and acne on the face and shoulders sometimes occur. Broad shoulders and slim hips are common. Often, Aries rising people are quick to smile, and they possess a youthful charm throughout life.
Probably early on in life, Aries rising people got typecast as the “independent” child. As adults, people with Aries Ascendants often stick to that role in life. People don’t run to help them out — they appear quite fine doing things on their own. These people have learned to be self-reliant, and this generally stems from their early experiences.
Despite a rather brusque and independent manner, these natives are usually very willing to compromise in their relationships, and are very attached to the people they hold dear. (Source).
