Introversion vs. Extroversion
Inner Reward or Exterior Excellence
The most important, defining & noticeable difference in any personality type is the introvert/extrovert question. The introvert draws energy from within and is far more sensitive to external stimuli than an extrovert. We work on batteries with a medium capacity for socialization; that battery requires frequent "re-charging" in order to avoid mental or emotional collapse. The introvert is far more reflective and reserved when it comes to interaction with others. The introverted person will often replay a scenario (future or past) in his or her mind, analyzing the key points of the exchange and evaluating the outcome or potential result. The extrovert, on the other hand, is very much in the 'moment' as far as socialization is concerned. The energy comes from the interaction itself, and extroverts thrive in roles with physical & instantaneous rewards or incentives.
The introvert will feel rewarded from inner self-assurance and more abstract incentives, like the ability to work independently or avoid unnecessary over-stimulation. It can be difficult to focus when more than one person is speaking or being spoken to.
