AQUARIUS (January 20–February 18)

In a Nutshell: The slogan "Question authority" was no doubt written by an Aquarius. You refuse to do anything just because it's "normal," conventional, or recommended by your elders. In high school, you were probably either the disaffected punk princess in combat boots, fishnets and electric-blue mohawk -- or the chess-club superbrain who read Sartre and observed the popular clique as an intriguing sociological phenomenon. Today, you crusade for progressive causes, resist traditional definitions of identity, and spend altogether too much time online. The only downside of your intellectually superior existence? You're so well versed in the worlds of logic and reason that you may have trouble opening up emotionally.

Best Cosmic Compatibility: Sagittarius. You need a partner who stimulates your mind, grasps big concepts, and gets excited about exchanging ideas. No matter how much time you spend together, the two of you never run out of topics to talk passionately about.

Worst Cosmic Compatibility: Cancer. The super-sensitive Crab loves to dive beneath the surface of your emotions. But to a detached Aquarian, this feels like drowning.
