This is the third post in a series, the topic of which is The Four
Personalities. If you have not read the first and second posts, I
encourage you to do so before continuing. Again, while I am perhaps
putting a unique spin on how I present The Four Personalities, I can
claim none of the substance of these posts to be my own creation: The
best and most accessible book I can recommend on the subject is
Personality Plus by Florence Littauer.
