The famous psychologist, Carl Jung, had a radical theory that there are only 16 major personality types in the world! It is still a theory, but, it is well-tested and has produced hundreds of personality inventories based on his work (the most famous being the Myers-Briggs Type Indicator). This link takes you to a free online min-version of the assessment to see which personality type you possess. (Remember, a personality type does not limit you! It just indicates your preferences for processing information and stimuli, and helps identify interactions/activities that might give you energy or drain your energy!)
