Guess what! I took the Myers-Briggs personality test, and found out that I'm an INFJ. The INFJ is also called "The Counselor." This has changed since the last time I took it, when I was in college. Then, I was an INFP, aka "The Healer." I wonder what changed.
I swiped the following from wikipedia to share with you:
INFJ (Introversion, iNtuition, Feeling, Judging) is an acronym used in the Myers-Briggs Type Indicator (MBTI) publications to refer to one of the sixteen personality types. The MBTI assessment was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types, which proposed a psychological typology based on his theories of cognitive functions. These theories were based on clinical observation, however, rather than the controlled studies required for acceptance by the modern field of cognitive psychology.
From Jung's work, others developed psychological typologies. Well-known personality tests are the MBTI assessment, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey. Keirsey referred to the INFJs as Counselors, one of the four types belonging to the temperament he called the Idealists. According to some sources, INFJ is the rarest personality type.
The MBTI instrument
- How they focus their attention or get their energy (Extraversion or Introversion)
- How they perceive or take in information (Sensing or iNtuition)
- How they prefer to make decisions (Thinking or Feeling)
- How they orient themselves to the external world (Judgment or Perception)
By using their preference in each of these areas, people develop what Jung and Myers called psychological type. This underlying personality pattern results from the dynamic interaction of their four preferences, in conjunction with environmental influences and their own individual tendencies. People are likely to develop behaviors, skills, and attitudes based on their particular type. Each personality type has its own potential strengths as well as areas that offer opportunities for growth.
The MBTI tool consists of multiple choice questions that sort respondents on the basis of the four "dichotomies" (pairs of psychological opposites). Sixteen different outcomes are possible, each identified by its own four-letter code, referred to by initial letters. (N is used for iNtuition, to differentiate it from Introversion). The MBTI is approximately 75% accurate according to its own manual.
- I – Introversion preferred to Extraversion: INFJs tend to be quiet and reserved. They generally prefer interacting with a few close friends rather than a wide circle of acquaintances, and they expend energy in social situations (whereas extraverts gain energy).
- N – iNtuition preferred to Sensing: INFJs tend to be more abstract than concrete. They focus their attention on the big picture rather than the details, and on future possibilities rather than immediate realities.
- F – Feeling preferred to Thinking: INFJs tend to rely on a personal, internal sense of right and wrong rather than external, objective criteria. When making decisions, they often give more weight to feelings and social considerations than to logic.
- J – Judgment preferred to Perception: INFJs tend to plan their activities and make decisions early. They derive a sense of control through predictability, which to perceptive types may seem limiting. 
 Characteristics of INFJs
INFJs are conscientious and value-driven. They seek meaning in relationships, ideas, and events, with an eye toward better understanding themselves and others. Using their intuitive skills, they develop a clear vision, which they then execute decisively to better the lives of others. Like their INTJ counterparts, INFJs regard problems as opportunities to design and implement creative solutions.
INFJs are quiet, private individuals who prefer to exercise their influence behind the scenes. Although very independent, INFJs are intensely interested in the well-being of others. INFJs prefer one-on-one relationships to large groups. Sensitive and complex, they are adept at understanding complicated issues and driven to resolve differences in a cooperative and creative manner. 
Accounting for 1–3% of the population, INFJs have a rich, vivid inner life, which they may be reluctant to share with those around them. Nevertheless, they are congenial in their interactions, and perceptive of the emotions of others. Generally well-liked by their peers, they may often be considered close friends and confidants by most other types. However, they are guarded in expressing their own feelings, especially to new people, and so tend to establish close relationships slowly. INFJs tend to be easily hurt, though they may not reveal this except to their closest companions. INFJs may "silently withdraw as a way of setting limits," rather than expressing their wounded feelings—a behavior that may leave others confused and upset.
INFJs tend to be sensitive, quiet leaders with a great depth of personality. They are intricately and deeply woven, mysterious, and highly complex, sometimes puzzling even to themselves. They have an orderly view toward the world, but are internally arranged in a complex way that only they could understand. Abstract in communicating, they live in a world of hidden meanings and possibilities. With a natural affinity for art, INFJs tend to be creative and easily inspired. Yet they may also do well in the sciences, aided by their intuition.
The following is also from wikipedia:
Counselors are introspective, cooperative, directive, and attentive. Counselors find helping others to personally develop and reach their potential to be personally gratifying as they have a strong desire to contribute to the welfare of others. Counselors often communicate to others in a personalized manner and are positive and kind when dealing with others. Counselors are good listeners and are highly intuitive. They are often able to detect the emotions or intentions of another individual before the individual is aware of them. Counselors are sometimes amazed at their ability to read the emotions of others and this extreme empathetic ability could be the psychological basis for premonitions, mind reading, and other psychic phenomena.
Counselors usually have intricate personalities and rich inner lives. They tend to keep their innermost thoughts and emotional reactions to themselves, which can make them tough to get to know. Counselors tend to be private people, possibly because their ability to take in the emotional experiences of others can cause them to be easily hurt. They have great depth of personality and can understand complex issues and individuals.
Counselors often prefer to work on a one-to-one basis with others or to work intensely with people close to them. Counselors are happy doing jobs that require solitude and close attention. They are also happy working with others provided that the personal interactions are not superficial and they are given some quiet time in order to reenergize themselves. Counselors usually exert their influence behind-the-scenes rather than being a visible leader.
Counselors often work well in organizations. They value staff harmony, are good at consulting and cooperating with others, and they are concerned with the feelings of others. They strive to make an organization run smoothly and pleasantly. Counselors can also act as a barometer of the feelings within an organization.
