Aries is the first of the twelve zodiac signs and is represented by the constellation Aries, the ram. 

If born under this sign, you're likely to be adventurous, dynamic, and competitive.  And going somewhere.  Anywhere, just so you’re moving. 

Aries are known for their quickness and leadership qualities, as well as a tendency to be impulsive (blame the "fire" element) and blunt - though they mean to just be straightforward.  Really, they do mean well (which they’ll tell you).
