ARIES (March 20 – April 19)

Element: Fire
Ruling Planet: Mars
M.O.: "I am"

In a Nutshell: As the first sign of the zodiac, Aries is all about beginnings -- you're constantly initiating new projects, ideas, and adventures. Driven and assertive, Aries women defy shrinking-violet feminine stereotypes and go barreling through barriers that get in their way. What you're not so good at is the follow-through; you're not big on patience and have a tendency to run out of steam faster than Lindsay Lohan's romances. Luckily, that roof-shaking temper of yours also blows over right away. With a sharp, straightforward Aries, what you see is pretty much what you get. Your loved ones can count on you to be direct and say what you mean.

Best Cosmic Compatibility: Libra. Rams rush headfirst into action without stopping to consider the consequences; the Scales spend time weighing all the options. Together, you can find a healthy balance between thinking and doing, give and take.

Worst Cosmic Compatibility: Virgo. You bulldoze right over timid people who try to micromanage details. Face it, does anyone really think Ryan Phillippe wears the pants in the family?

Famous Aries Men: Heath Ledger, Elton John, Matthew Broderick, Zach Braff, Pharrell Williams, Steven Tyler, David Letterman, Hayden Christensen, James Franco, Adrien Brody, Vince Vaughn
