Introvert Versus Extrovert: What really is the difference?
Not much actually.
Most people call themselves (self-identified at that) an "introvert extrovert" stating that they like to be around people "sometimes".
I've seen conversations where people are self-identifying as introvert or extrovert, assuming that this means if they like to be around people or not.
Introversion and extroversion has very little to do with socializing preferences. It has to do with processing.
For instance, if you assume you are an introvert because you assume that because you prefer private time, to parties, but are often asking your friends (or Facebook's) opinions; it means you are probably more of an extrovert thinker. An extrovert, by etymology means, to "turn outward and beyond" where an introvert is to "turn within".
For the most part, not "liking" people or wanting to be around people ever, means you might have attachment issues or isolation. It has nothing to do with introversion vs extroversion.
At the same time, yes, people who want others opinions to help them process through their lives, tend to, by the very nature of gleaning opinions, talk to others more. They tend to talk to friends on the telephone, on social networking and out in crowds. They thrive off of interactions, but it doesn't mean that they like people less or more. In fact, some "extroverts" will ask a myriad of people opinions, they will socialize often and then come into the therapy room telling me how they do not like most of the people (or all )in their lives.
I have seen introverts, those who do not seek interaction reactions, or glean others opinions, thus seek out socializing for that reason alone, still enjoy deep, meaningful interactions and socializing and have nothing but positive words for their friends and relatives.
I have seen "extroverts" not be able to make it up the corporate ladder because they cared too much what others think, and I've seen introverts become leaders because they seemed immune to other's opinions.
This is not to say that introversion or extroversion is a key to success or failure, or meaningful relationships. It simply means that the ability or enjoyment of socializing is very separate from how one processes. You might see some very social people who are actually introverts, meaning, they simply want to be friendly for the sake of friendship. They might see you offering an opinion as boundary crossing. An extrovert might welcome your opinion as they process with this navigation.
We all have differing processing; so how you process relationships might be introverted, but work might be extroverted. Or, you might be more introverted in processing or extroverted.
You could be very shy, and have one friend and ask that friend frequently, for their opinion. That would make you more extroverted in thinking and processing. You could be very outgoing and not really ask others opinions nor set up opportunity to welcome their opinions and I would consider you an introverted processor.
All are fine, all are just variations and none should be taken too seriously unless your asking for opinions or keeping it internal, is getting in the way of your happiness or function.
Now, that being said, how do you define yourself? Do you prefer to ask others opinions and like to learn by compare and contrast, or do you prefer to observe and analyze?
