This fiery sign is the first sign in the zodiac. Aries rule with the head and lead with the head, quite literally, propelling themselves forward on adventures, climbing corporate ladders, and embracing independence. Aries people are an energetic bunch — passionate, courageous, free-spirited, and somewhat turbulent. To every positive, there's always a darker underbelly. Jealousy, impatience, moodiness, and impulsiveness might be your struggles. If you can keep those things in check, an Aries has the ability and energy to lead an exciting, adrenaline-filled, successful life.
