I'm not sure if I believe, though the information in detailed horoscopes and astrological books has been correct in relation to me, go so far as to describe the relationship between me, my grandmother, and cousin in detail.
The reason i doubt is because there are actually 13 signs and we ignore the 13 and as a result no one's sign is actually their sign so I mean its hard to put an credence to a broken system.
Sagittarius is the ninth astrological sign in the Zodiac, originating from the constellation of Sagittarius. In western astrology, the sign is now no longer aligned with the constellation as a result of the precession of the equinoxes. Sagittarius is considered a "masculine", positive (extrovert) sign. It is also considered a fire sign and one of the four mutable signs. Sagittarius is ruled by the planet Jupiter. Being the ninth sign of the zodiac, Sagittarius has been associated with the astrological ninth house.

Good Sagittarius Personality Traits

The good news is, sagittarians are one of the luckiest signs out there. If you are a Sagattarius then you most likely never worry and won't ever need to waste your days worrying. You are a very positive person and a great listener. People love to be around your positive attitude and enjoy your positive influence on themselves. As a sagittarius you are also known for your large heart and willingness to give a helping hand to anyone that asks. The positive energy you carry is influenced from the planet jupiter (the largest planet in the solar system) and is responsible for keeping a smile constantly on your face and the people around you.

Your optimisim and big ideas are always helpful in the workplace when you are given the freedom you require to express yourself. One of the strongest qualities of a sagittarian person is their imagination. This imagination fits in with the symbol of the sagittarius. The symbol is an Archer half man/ half horse which symbolizes the attempt to free it's self fro the grasp of a mythic animal.

Physically speaking, Sagittarians are the most aware of their own bodies. They are constantly going for the perfect body and the gym is often like a second home. You truly understand how to enjoy life while being healthy and physically fit. Anytime you incorporate looking great and feeling great, you are at your happiest point. Sagittarius people attract many romantic partners as everyone wants to know the secret to your constant happy moods and unlimited energy.

Bad Sagittarius Personality Traits

Unfortunately every sign must have a few bad characteristics but these are not necessary the worst. Although sagittarius people can become easily bored as their imagination wanders on a daily basis, they are never a shortage of entertainment as they are honest to a fault. Truth and honor are the most important things to sagittarians and it never ceases to get them in trouble. A sagittarian person will never "bite their lip" and will say what's on their mind. They are constantly avoiding most difficult situations under the guise of boredom or over analyzing them until it drives them crazy. This honest bug is not one that will ever go away and it does not help that the sagittarian sign is known for being very blunt and over confident.
