One of the most popular reasons for someone to check their horoscope is to discover their best love match — their soul mate. Everyone at one time or another is curious to see what the stars say about the person who might complement them above all others. Some sun signs seem to be made for one another, while others would be best simply as friends.

Each person is born with the planets aligned in a particular way to make them unique from all others, and finding a companion who shares those same qualities can be intimidating. Some of the best matches found in the zodiac are those that balance each other. Those within the same element group share common traits that make for great business partnerships, friendships and marriages.

There are four elements in the zodiac: Fire, Earth, Air and Water. The signs that fall within those elements are as follows:

Fire Signs: Aries, Sagittarius and Leo. They are energetic and active, passionate, outgoing, and impulsive. Earth Signs: Taurus, Capricorn and Virgo. They are practical, patient, stable and industrious. Air Signs: Gemini, Aquarius and Libra. They are expressive, intelligent, rational and broad-minded. Water Signs: Cancer, Pisces and Scorpio. They are intuitive and emotional, empathetic, creative, and imaginative.

Any combination within these groups will do well in marriage. They possess the same qualities to keep their companion attracted and interested in one another in all areas.

There are, however, some sun signs that are simply incompatible with each other no matter what their circumstances and make for the absolute worst matches in the zodiac. Same-sign marriages tend to become disastrous unions. The couples are simply much too similar to form a well-balanced attachment. They tend to drown each other in their own traits and qualities. The dominant and aggressive sign of an Aries couple are both too eager for competition with one another to be successful in marriage. A couple sharing the sign of Pisces are both too emotional and dependent and tend to drown each other in confusion and self-indulgence. Three possible exceptions to this are Leo, Libra and Aquarius. The couples sharing these signs have a possibility to work hard with one another to make their marriage successful.

Other romantic attachments that might prove unsuccessful and doomed are:

Aries and Scorpio: Both are independent and want to control each other. Taurus and Aquarius: Taurus is demanding and possessive, while Aquarius looks for openness and self-expression. Gemini and Cancer: Cancer is sensitive and needs reassurance, while Gemini has a sharp tongue and can be brutally frank.

Cancer and Libra: Moody Cancer becomes insecure with airy Libra’s aloofness. Leo and Virgo: Leo is extravagant, while Virgo is conservative. Virgo and Aquarius: Aquarius is outgoing and inventive, while Virgo is reserved and practical. Libra and Capricorn: Libra is easygoing and sociable, while Capricorn is hardworking, disciplined and more of a loner. Scorpio and Sagittarius: Scorpio wants security and is more of a homebody, while Sagittarius wants adventure and travel. Sagittarius and Capricorn: Capricorn is cautious and thrifty, while Sagittarius is venturesome and free spending. Aquarius and Scorpio: Aquarius is looking for adventure, while Scorpio wants commitment. Pisces and Leo: Pisces is introspective and dreamy, while Leo is outgoing and domineering.
