"ISFJ: Introverted, Sensing, Feeling, Judging

ISFJ's are friendly, conscientious, and responsible. Soft spoken (ha) and committed to painstaking accuracy, you are very good at meeting deadlines and fulfilling obligations. You strive to maintain order and harmony in your life. You are also very considerate and loyal, remembering details about those who are important to you.

Best jobs for you: nurse, researcher, career adviser, teacher, lawyer, homemaker, childcare provider or early childhood developer, counselor or social worker, clergy or religious worker. "
