[Prudence]

Apparently I've transitioned from an ISTJ to an INTJ (not much of a move, really, as I was just on the S side of the continuum and now I'm just on the N side.)

Your personality type:

Independent, original, analytical, and determined. Have an exceptional ability to turn theories into solid plans of action. Highly value knowledge, competence, and structure. Driven to derive meaning from their visions. Long-range thinkers. Have very high standards for their performance, and the performance of others. Natural leaders, but will follow if they trust existing leaders.

Careers that could fit you includes:

Scientists, engineers, professors, teachers, medical doctors, dentists, corporate strategists, organization founders, business administrators, managers, military, lawyers, judges, computer programmers, system analysts, computer specialists, psychologists, photographers, research department managers, researchers, university instructors, chess players.

At least lawyer is in there somewhere.
