Do you know your zodiac sign? Do you ever wonder why people have certain personality characteristics? These twelve signs could explain these questions and give you insight into your future and your relationships.

There are two ways to group the twelve signs. The first way is to divide them into four groups, based on the four elements. Aries, Leo and Sagittarius are in the Fire group. Fire signs are very intense and exciting, inspirational and imaginative. Taurus, Virgo and Capricorn are in the Earth group. Earth signs have characteristics such as common sense and stability. Gemini, Libra and Aquarius are in the Air group. Air signs are very sociable and intellectual. Lastly, Cancer, Scorpio and Pisces are in the Water group. Water signs are very emotional and have great intuition.

The second way to group the zodiac signs is to separate them into three modes. The three modes are based on creativity. Aries, Cancer, Libra and Capricorn are in the first mode called Cardinal. Cardinal signs are inclined to initiate change. They cause things to happen. Taurus, Leo, Scorpio and Aquarius are in the mode called Fixed. Fixed signs are inclined to sustain, preserve, endure and solidify change. They are very focused and determined. Gemini, Virgo, Sagittarius and Pisces are in the last mode called Mutable. Mutable signs are very adaptive and flexible. They take things and attempt to adapt or alter them.
