INTJ

INTJs lead with Introverted Intuition (Ni), which makes them inclined to abstract the future. They are prone  to symbolic, metaphorical and philosophical thinking, or anything that will point them to timeless truths  that can help them mentally transcend time to predict forthcoming events. INTJs often try to map out their  whole life from an early age and can also have hunches about how events or interactions will likely play  out that are not readily evident to anybody else, and may struggle to articulate complex ideas that make  perfect sense in their own mind. 

Their auxiliary function is Extraverted Thinking (Te), which makes them extraverted towards external logic  and inclined to absorb facts and data in service of being productive and efficient. They usually do not feel  the need to work things out by themselves what has already been worked out by other people. They may  sometimes ignore the underlying logic of what they are doing for the sake of results, and they have a strong  urge to organize and work and often have tremendous stamina. 

Their tertiary function is Introverted Feeling (Fi) which are the personal feelings and values of the INTJ.  Though this type generally prioritizes logic and productivity over emotions, they are relatively in touch  with their feelings, values and personal identity and they still care about people in their lives, even if they  are not always good at showing it. 

Their inferior function is Extraverted Sensing (Se) which is their hidden desire to live in the moment and  forget about the future. INTJs can be attracted to asserting themselves, to physical activities, or to bouts of  hedonism, without ever feeling completely natural or comfortable in such roles. They can enjoy the  company of more extraverted types in small doses who can serve as their guide or stimulate what they  struggle to maintain in themselves.  

INTJs are known for their strategic thinking and high expectations, both of themselves and others. They are  typically very independent and confident in their abilities. They approach life with a plan and are always  looking for ways to improve systems and make things more efficient.
 

INTJs excel in fields that allow them to use their analytical skills to solve complex problems, such as  engineering, law, and science. They are long-term thinkers, often able to see the potential outcomes of a  situation well before others. 

Although they may appear reserved, INTJs are deeply committed to their goals and will work tirelessly to  achieve them. They value knowledge and competence, and they respect others who take the time to develop  expertise in their field. INTJs have a strong inner vision and are often driven by their desire to make meaningful  changes in the world.
