Along with Pisces, this is the rarest Rising because these two signs take the shortest amount of time to rise in the northern hemisphere - a rare breed!
Goals and Setbacks
Aries Rising has an overwhelming desire to win, an energetic driving force, and a remarkable energy reserve. Ruthlessness can be a problem, although competition is generally an excellent spur. There are many strong and positive traits in this placing, but perhaps this person needs to learn to step back a little and take a closer look at what they are doing and why they are doing it.
You strip away everything that is not necessary to the achievement of your goals, whether these are immediate or long term; the menu of tonight's dinner, or the details of a contract. Your ability to see clearly the essential elements of important decisions is both enviable and convincing.
Personality
In contrast to the independence of Sun sign Arians, those with Aries rising have a very strong need for a permanent partner, and they can be surprisingly understanding, compassionate and tolerant of their loved ones. You want to stand out from the crowd, being born with the will to succeed. You tend to be direct in your approach, and have the Arian potential to cope in a straightforward way with the day to day problems of life. Your friendship must be warm and on the level. Let me put it this way: you are a fine friend, and a formidable foe. Things are never done by halves. You may expect total devotion and sincerity in friendship, but in turn, you extend a loving and strong hand.
Symbolism
Aries is the first sign of the zodiac. As it represents birth, the Aries Rising is many times conscious only of themself. The infant of identity completely absorbed with their own toes and fingers. The needs of the Aries Rising come first. When the Aries Rising has something they want to get off their mind, they'll call you at 4 in the morning without a qualm. Why shouldn't you be awake to listen to them? They're awake. That's all that counts. But who could call the small baby truly selfish? It's hard to resist a baby, because they're so totally unaware that they're causing anyone the slightest inconveience. Like the innocence of the newborn, your Arian aggressiveness softens your egocentricity.
