I was born in December and this is what it says about me:
Like an archer's arrow that always finds its target, and because Sagittarius is governed by the planet of luck and expansion, Jupiter, it is said that Sagittarians are prone to finding themselves in the best of fortunes. Just as the archer always wants to shoot straight and true, honesty, truth, and integrity are said to be of the greatest importance to the Sagittarian. Like the members of their fellow fire signs, Leo and Aries, they are said to be direct, forthright, independent, positive, optimistic, enterprising, trustworthy, and loyal.
Sagittarians are said to be natural teachers and philosophers, with little or nothing giving them more pleasure than revealing to others the many necessities that appear to govern the universe. If there are unnatural laws at work anywhere, the typical Sagittarian, it is said, won't feel at ease or rest until natural laws have supplanted them.
However, as with any kind of worship, Sagittarians should be capable of becoming fanatical - the fanatical slaves of the rituals and conventions they love. For instance, they may become rebels merely for the sake of being rebels, become hypocrites in religious belief merely because they find that the form not the beliefs of the practice satisfies them, or become political turncoats where flattery and deceit can help them to achieve their ambitions.
It is said that Sagittarians seldom betray a personal trust and make good friends and companions, even though their tendency to say exactly what is on their minds can be a painful to others, and they're readily able to use their ability to find sources of weakness and then wound by attacking them. But although they can dish out pain, they are also supposed to be able to take it, because it is said that if they have what they consider to be a just cause to fight, they'll defend it doggedly without concern for their own well-being. It is said that they are fundamentally generous people, but that they can sometimes seem to be mean because of their tendency to be constantly on their guard, which contrasts somewhat with their natural restless enthusiasm that is too optimistic to allow anything to rain on their parade.
Sagittarians are supposed to long for new and exciting experiences, to be able to roam freely and unrestrained, which, it shouldn't be surprising, makes them inclined to travel to exotic destinations where they can indulge themselves in unconventional and exciting diversions. Of course, if this is true, it's probably equally true that they don't allow relationships to develop roots.
Occupations and interests that Sagittarians are drawn to are supposed to involve politics, teaching, the law, religious pursuits, the armed forces, advertising, horse-trading, and bookmaking. A tendency to be restless is said to make regular changes of occupation inevitable.
