Extraverted people are more outwardly directed; the movement of libido or personality moves outward; which means they seek out objects, words, situations, characters of the outward world and Introverts move these things inwards drawing these things within them and in relation to themselves, essentially relating everything of the external world to their self, where they become the center of their observations; hence, for Introverts, libido is inward directed. Best way to imagine this is if there is breath within the person and it is flowing outwards and trying to reach as much space outside as possible, this would be Extraverts; while for the Introverts this breath already exists outside and the introvert is trying to breath it inwards.
Level of activity, inward directed or outward directed, distinguished Extraversion or Introversion; for instance, I'm an classic Introverted attitude; I do a lot of reading but even thought this amount of work is energy and productivity I am doing it for different purposes; I, unlike Extraverts, am not looking at stuff outside of me, more stuff I just want to get down and share; a typical Extraverted blog like The MovieZombie (themoviezombie.blogspot.com) draws on information, or FACTS and observations, while mine is more based on internal intuition, my gut about things.
