The sign we are taking about here is astrological ones. Most people do believe in astrology.
How does one say that the sign affects them or that, they are ruled by it? How can the sun, the moon or the planets affect us from so far away? According to the astrologer they do! The whole branch of astrology would disintegrate if the soothsayers did not perpetuate those.
Most of my acquaintances do say that I am a typical Aries. Now what is a typical Aries? Aries is the first sign of the zodiac. Also known as the baby. Akin to a baby, they seldom think of the consequences and simply surge ahead, ramming hard, hurting own selves in the process. No wonder the Ram is their symbol.
What does being an Aries means to me? That is somewhat easy to answer. It means being straight forward, direct and forthright. I cannot beat around the bush ever. I am quick-tempered which subsides easily enough. I like new challenges. I thrive on those. I can make friends easily enough and stick to them, no matter come what may.
I can adapt to any situation. Adverse circumstances do not affect me for long. Material things are not as important as cultivating relationships.
I can take up an issue and follow it to the end if I am so inclined. I do need instant results due to my impatience. I might leave things half way through and start on a new venture. I constantly need to do new things or else I get bored easily enough.
Impulsiveness is one trait, which lets me down. I do not think much ahead and just plunge in, getting hurt in the process. Mind you, I do pick myself, brush up and get on with life. There is no other way for me.
I am always open to new ideas, new adventures, and new way of thinking. If I set my mind to it, no one can divert me from my purpose.
I describe here only a miniscule part of what I am. If it means that I am an Aries, I suppose I am. Cinquain, in a nutshell:

Aries
So courageous,
Accepting challenges
Quick-witted and quick-tempered
Ram hard!
As I mentioned some place else, I got bored describing myself and hence leaving it here!
However, I would like to add that more than signs (sun or moon or whatever), our genetics and surroundings play major rolls in shaping us.
