Carl Jung proposed that there are 16 different personality types. The Myers-Briggs Type Indicator is a questionnaire based around these personality types. There are many different tests throughout the internet, but this one is probably the most accurate. All the tests I've taken throughout the years always tell me I'm an INTJ.
INTJs are one of the rarest of the sixteen personality types, and account for about 1–4% of the population. Hallmarks of the INTJ include independence of thought and a desire for efficiency. They work best when given autonomy and creative freedom. They harbor an innate desire to express themselves by conceptualizing their own intellectual designs. They have a talent for analyzing and formulating complex theories. INTJs are generally well-suited for occupations within academia, research, consulting, management, science, engineering, and law. They are often acutely aware of their own knowledge and abilities—as well as their limitations and what they don't know (a quality that tends to distinguish them from INTPs). INTJs thus develop a strong confidence in their ability and talents, making them natural leaders. In forming relationships, INTJs tend to seek out others with similar character traits and ideologies. Agreement on theoretical concepts is an important aspect of their relationships. By nature INTJs can be demanding in their expectations, and approach relationships in a rational manner. As a result, INTJs may not always respond to a spontaneous infatuation but wait for a mate who better fits their set criteria. They tend to be stable, reliable, and dedicated. Harmony in relationships and home life tends to be extremely important to them. They generally withhold strong emotion and do not like to waste time with what they consider irrational social rituals. This may cause non-INTJs to perceive them as distant and reserved; nevertheless, INTJs are usually very loyal partners who are prepared to commit substantial energy and time into a relationship to make it work. As mates, INTJs want harmony and order in the home and in relationships. The most independent of all types,[16] INTJs trust their intuition when choosing friends and mates—even in spite of contradictory evidence or pressure from others. The emotions of an INTJ are hard to read, and neither male nor female INTJs are apt to express emotional reactions. At times, INTJs seem cold, reserved, and unresponsive, while in fact they are almost hypersensitive to signals of rejection from those they care for. In social situations, INTJs may also be unresponsive and may neglect small rituals designed to put others at ease. For example, INTJs may communicate that idle dialogue such as small talk is a waste of time. This may create the impression that the INTJ is in a hurry—an impression that is not always intended. In their interpersonal relationships, INTJs are usually better in a working situation than in a recreational situation. INTJs are perfectionists, with a seemingly endless capacity for improving upon anything that takes their interest. What prevents them from becoming chronically bogged down in this pursuit of perfection is the pragmatism so characteristic of the type: INTJs apply (often ruthlessly) the criterion "Does it work?" to everything from their own research efforts to the prevailing social norms. This in turn produces an unusual independence of mind, freeing the INTJ from the constraints of authority, convention, or sentiment for its own sake.Wikipedia

INTJs are analytical. Like INTPs, they are most comfortable working alone and tend to be less sociable than other types. Nevertheless, INTJs are prepared to lead if no one else seems up to the task, or if they see a major weakness in the current leadership. They tend to be pragmatic, logical, and creative. They have a low tolerance for spin or rampant emotionalism. They are not generally susceptible to catchphrases and do not recognize authority based on tradition, rank, or title.INTJs are strong individualists who seek new angles or novel ways of looking at things. They enjoy coming to new understandings. They tend to be insightful and mentally quick; however, this mental quickness may not always be outwardly apparent to others since they keep a great deal to themselves. They are very determined people who trust their vision of the possibilities, regardless of what others think. They may even be considered the most independent of all of the sixteen personality types. INTJs are at their best in quietly and firmly developing their ideas, theories, and principles.—[15]

Personal relationships, particularly romantic ones, can be the INTJ's Achilles heel. While they are capable of caring deeply for others (usually a select few), and are willing to spend a great deal of time and effort on a relationship, the knowledge and self-confidence that make them so successful in other areas can suddenly abandon or mislead them in interpersonal situations.
This happens in part because many INTJs do not readily grasp the social rituals; for instance, they tend to have little patience and less understanding of such things as small talk and flirtation (which most types consider half the fun of a relationship). To complicate matters, INTJs are usually extremely private people, and can often be naturally impassive as well, which makes them easy to misread and misunderstand. Perhaps the most fundamental problem, however, is that INTJs really want people to make sense.

Eerily accurate. People may interpret my silence and stiffness as awkwardness, but to be awkward requires you not to understand social rituals. I understand them perfectly fine (except for flirting, that shit's worse than calculus). It's just that I consciously choose not to partake in the rituals I deem stupid. Why should I? If I don't like it, then I'm not doing it. My friends who are annoyed at my outright refusal to drink or dance unironically will know what I'm talking about. OOPS, INTJ, YOUR PROBLEM NOT MINE, DEAL WITH IT, WHOOPSIE, INTJs REPREZENT FUCKERS.
