Known as The Cusp of Revolution, the Scorpio/Sagittarius cusp is full of strength and rebellious energy. Individuals born on this cusp possess the bold, aggressive qualities of Scorpio along with the active and adaptable traits of Sagittarius.

Scorpio/Sagittarius cuspers are likely to be accomplished, because they have that intense Scorpio passion combined with the typical Sagittarius way of charging right into action. But sometimes they are so action oriented they can be characterized as rebellious -- and maybe even accused of running wild.

Rebelliousness doesn't need to be a bad thing, though. It often simply means these cuspers are open-minded, freedom-loving and willing to speak their minds frankly.

Because of the forthright nature of those born on the Scorpio/Sagittarius cusp, conflicts can arise with figures of authority. Therefore these individuals may do better when self-employed, and if they can find work that befits their natural tendencies toward empathy for the human condition, even better.

The greatest challenge for those born on the Scorpio/Sagittarius cusp is to reconcile the very opposite nature of these two Fire and Water signs. If not, they may be a bit misunderstood. But if they can learn to balance their complex personalities, they will likely become humorous, powerful and generous people.

General Behavior of the Thinker: What is important to understand about Fives is that they are not insecure about their capabilities. What they fear they lack are the inner resources necessary, such as time and energy, to cope with life. They tend to hoard these resources, and protect them fiercely. This is the reason for their detachment. They don't want to be imposed upon. In order to protect themselves from an intrusive world, and from insufficient resources, Fives take refuge inside their minds. They detach from feelings and rejects claims to their time, energy and emotions. They reduce their needs and focus on pursuing self-sufficiency.

The challenge of Fives is their inability to open themselves up to anything that can threaten their peaceful world, even their own emotions. They are not comfortable in dealing with the demands of a relationship or competing for their place in the world. They'd rather ponder, and study, and get involved only in things that they've mastered. This personality does not like putting themselves in a position of vulnerability. They are non-intrusive and very independent.

Because of their desire to hide their perceived weaknesses, they do not ask for help, even if people are happy to assist them if they needed assistance.

Fives usually have few friends, but they last for a lifetime.
