Ah, the Enneagram. An ancient personaltiy type indicator, of either Christian or Sufi (mystical Muslim) origin. In my brief quiz, I actually tied as two types (click on them for more in-depth descriptions):
The caring, interpersonal type. Twos are empathetic, sincere, and warm-hearted. They are friendly, generous, and self-sacrificing, but can also be sentimental, flattering, and people-pleasing. They are well-meaning and driven to be close to others, but can slip into doing things for others in order to be needed. They typically have problems with possessiveness and with acknowledging their own needs. At their Best: unselfish and altruistic, they have unconditional love for others.
The perceptive, cerebral type. Fives are alert, insightful, and curious. They are able to concentrate and focus on developing complex ideas and skills. Independent, innovative, and inventive, they can also become preoccupied with their thoughts and imaginary constructs. They become detached, yet high-strung and intense. They typically have problems with eccentricity, nihilism, and isolation. At their Best: visionary pioneers, often ahead of their time, and able to see the world in an entirely new way.
I think those are fairly accurate.
