Personality type describes individual differences using four elements: energy style (introversion or extraversion), cognitive style (sensing or intuition), values style (thinking or feeling), and life style (judging or perceiving). There are 16 personality types that result from combining one trait from each element, such as ENFJ which stands for extraverted, intuitive, feeling, and judging. Knowing your personality type can help you understand your strengths, weaknesses, and how to find fulfillment in your career and relationships.
