Myers-Briggs Type Indicator. It's absolutely fascinating stuff. From Wikipedia: "Myers-Briggs Type Indicator (MBTI) is a personality test designed to assist a person in identifying some significant personal preferences."
Many modern psych tests are based on the same principles adopted in the MBTI. I reckon you are a ENTJ.
You can take a quick test at
