Psychologically speaking, an introvert looks within, while an extrovert outside themselves. An introvert is not shy, as they can talk up a storm in any group, and maybe even get a following. Rather, they seem to like a lot of ALONE TIME to recharge. I'm like that. Don't need people to cheer me up, and I spend time alone with God and that's when I get some good quality time learning.
Come and think of it, that's like a cat, which is why I like them. If you go away for awhile then come home, they look at you as if to ask, "Do I know you? Oh, by the way, fill up my cat dish with food."
Independent.
And extrovert seems to need people to recharge. I would find that suffocating, but that's how some people are and that's just them -- nothing wrong with that. They are more the team players and life of the party. Reminds me of a dog that is so happy to see you home that they jump all over you reminding you that they almost had a nervous breakdown for the 3 hours you were gone.
Another thing I noticed is that the introverts are the cautious thinkers -- downside is that an extreme of that nothing gets done, but they think a lot about it! The extroverts are the fearless doers -- downside is that by doing so to the extreme, big mistakes can be made and are people with the reputations of putting their foot in their mouth because they are more impulsive and don't think first.
Being an introvert myself, needless to say that those are the people I favor more, their company. Then we don't feel so bad if we say to each other, "Get outta my hair for a few hours and get lost." To which the other Introvert will reply, "I was thinking the same thing. Don't mind if I do." But they'll come back together and still be friends later because they understand each other. Introverts have tendencies to be
empaths, but that's a subject in and of itself.
