Classification of characters based on quality:

Cardinal:

Aries, Libra, Cancer, Capricorn (beginning of seasons) - are active and dynamic. They go through a lot of problems in order to achieve significant results. During the life the undergo many changes and crises which are followed by great successes. Their strength lies in the persistence but chaotic energy usage diminishes their success. They often attract each other but these relationships usually end in a bad way because each of them is responsible for their share of Zodiac, they want to be the rulers and they are successful in that. Aries wants to put Libra in a subordinate position and is doing everything to succeed, but usually at the end Libra uses Aries for her own goals.  Equally dangerous antagonists are Cancer and Capricorn.

Fixed:

(unchangeable): Taurus, Leo, Scorpions, Aquarius - in the period of their ruling, the season become mature. They are stable, reliable people, possess great mental and physical energy, a strong will and passion. They are stubborn, dignified, like honours. They are guardian angels of the world. As pioneers, explorers and leaders they reach leading position which then jealously guard, enjoying the results of painstaking years. There are frequent relationships between them, some of which are ideal, like Leo - Aquarius and Taurus - Scorpio. Taurus - Scorpio is the most ideal of 144 possible combinations between signs (12 x 12). But even if in such ideal relationship there is a huge attraction, it takes a lot of good will on both sides to maintain the relationship through the time. They stand opposite to one another, they are allies who can become antagonists.

Variable:

Pisces, Sagittarius, Gemini, Virgo - their period is marked by end of seasons. They are sensitive, nervous; they think a lot and talk a lot. They are adaptable but they give up once they reach an obstacle. They are difficult to follow. The signs opposite up to 180 ° are attractive for them.  Gemini seek Sagittarius, Pisces and  Virgo.
