Libra is the seventh sign of the zodiac which means that it's right at the dividing line between the first half of the zodiac and the second half of the zodiac and therefore it's considered the sign of balance. Not necessarily that Librans are balanced but they look for balance. They want this in their lives, in their work, certainly in their relationships. Librans are the sign also that are best in partnership. Librans don't like being alone, don't like to cope and make decisions and struggle through life alone. So Librans are natural partners.
The thing with Librans, however, are that Libra also has an elegance, a style, a creativity, an artistry and loves being honored for that, loves being in a certain limelight. So Librans share that quality with other signs in the zodiac of wanting to be in the center or wanting to have a lot of attention. Librans feel incomplete without an other and therefore they can very often in life make perhaps bad choices, or unwise choices in love because they want to be in a relationship and sometimes don't stop to figure out whether this person really, really is truthful. So Librans lesson in life is how to be in a partnership but how not to lose it's self.
