Jealousy can be an issue on both sides. However, you can make an excellent team if you respect each other's strengths. Taurus is practical and sophisticated, a grounding force that streamlines the Archer's expansive visions. Between the Bull's business acumen and Sag's charisma, you can build an empire—especially with your driven work ethics. You both have a ribald, lusty side to your personalities and misbehaving together can be a blast.
With your hot tempers, you can go from zero to sixty fast, and arguments can be explosive. Your peace treaties should always take place at the dinner table. Sagittarius is ruled by Jupiter, god of the feast; Taurus by Venus, planet of pleasure and love. Gorging your bottomless appetites awakens a primal instinct in you both—you'll be tearing each other's clothes off before the second course.
You're opposite signs that actually have much more in common than this label suggests. Gemini rules the so-called "lower mind": common sense, reasoning, facts, hard data and intellect. Sagittarius governs the "higher mind": wisdom, philosophy, consciousness, ethics, metaphysics. Together, you find sweet neurological nirvana. You're both restless adventurers who hunger for knowledge and experience.
