ISTP
Introverted. Sensing. Thinking. Perceiving.

One of the 16 personality types from the Myers-Briggs Type Indicator (MBTI), ISTPs are estimated to make up roughly 4% of the population. Confident and capable, they often stir up excitement and are seen as natural leaders. ISTPs never let rules or bureaucracy get in the way of their goals, for they are true free spirits. Feeling the need to live on the edge, they take on steep risks but deliver results. While they are unlikely to converse loosely, they make up for their reserved demeanor with insightful and witty one-liners. Being thinkers and realists, they are logical and skilled at seizing the moment and making the most of it. Needless to say, they get a lot of pussy.
