http://www.typealyzer.com/ will try to determine your Myers-Briggs type from your journal (unfortunately, it doesn't explain what is being considered). It was close, but not entirely accurate on mine. It guessed ISTJ, while the test I did as part of a workshop in November said ISFJ. Here are descriptions of both:
ISTJ
Quiet, serious, earn success by thoroughness and dependability. Practical, matter-of-fact, realistic, and responsible. Decide logically what should be done and work toward it steadily, regardless of distractions. Take pleasure in making everything orderly and organized - their work, their home, their life. Value traditions and loyalty.
ISFJ
Quiet, friendly, responsible, and conscientious. Committed and steady in meeting their obligations. Thorough, painstaking, and accurate. Loyal, considerate, notice and remember specifics about people who are important to them, concerned with how others feel. Strive to create an orderly and harmonious environment at work and at home.
