Your are ISTP
ISTP is also known as STRATEGIZER
Cool onlookers. Quiet, reserved, observing and analyzing life with detached curiosity and unexpected flashes of original humor. Usually interested in impersonal principles, cause and effect, how and why mechanical things work. Exert themselves no more than they think necessary because any waste of energy would be inefficient. Action-oriented, precise and tireless. Can be impulsive. Challenged by complex equipment. Somewhat solitary.
