ISTP Development Booklet

ISTPs take their energy from the inner world of thoughts (and, maybe, emotions). They prefer dealing with facts and making decisions on a logical basis. Psychological Type Indicator (PTI) booklets provide an easy-to-understand reference for this type (based on Carl Jung's psychological type theory). Each booklet also includes a one page overview on each of the four relevant preferences. These pages make suggestions regarding time management, conflict, careers and general personality hints.
