A Short Definition of your Highest Score
Intrapersonal - the ability to assess one's own strengths, weaknesses, talents, and interests and use them to set goals, to understand oneself to be of service to others, to form and develop concepts and theories based on an examination of oneself, and to reflect on one's inner moods, intuitions, and temperament and to use them to create or express a personal view. Possible vocations that use the intrapersonal intelligence include planner, small business owner, psychologist, artist, religious leader, and writer.
Yep, when I say deeply introspective, I really mean it.
