INFJ
INFJs are intuitive, caring, quiet and peace-loving: deep and complex people who may seem equally at home dealing with the personal and analytical spheres of life. The interior world of vision and ideas is this type's most comfortable domain, but some degree of human connection is essential for the INFJ's happiness; a potential conflict for this type. Articulate, empathetic and idealistic, INFJs often say they just know things, they know them directly, and they may not be able to tell you how or why! INFJs seem to be able to feel others' feelings vicariously and sense the good and evil in situations: an almost psychic ability which may be an asset in many "people professions." Spiritual, sensitive and committed, INFJs enjoy being of service to others. Once this type's goals are set and the mind is made up, no argument based solely on reason and practicality is likely to divert the passionate INFJ from a mission or chosen project. Whether this characteristic manifests itself as admirable tenacity or bull-headed stubbornness may determine the individual INFJ's potential for life success.
Relationships
INFJs are warm and affirming people who are usually also deep and complex. They're likely to seek out and promote relationships that are intense and meaningful. They tend to be perfectionists, and are always striving for the Ultimate Relationship. For the most part, this is a positive feature, but sometimes works against the INFJ if they fall into the habit of moving from relationship to relationship, always in search of a more perfect partner. In general, the INFJ is a deeply warm and caring person who is highly invested in the health of their close relationships, and puts forth a lot of effort to make them positive. They are valued by those close to them for these special qualities. They seek long-term, lifelong relationships, although they don't always find them.
