I was talking to a friend the other day about what it means to be introverted/extroverted. We were speculating the nature of this strange trait. Is it an attitude, a characteristic, a preference?
Today, I realised that one way to look at introversion/extroversion is as a mode of fulfillment.
There are two ways in which a human can be fulfilled. One is through relationships with others, the other is through self-fulfillment. In a venn diagram, the overlapping intersection would be, I suppose, odd things like relations to entities like God, music and other abstractions.
Being fulfilled through relationships with others involves surrendering to the feelings you get when you are in the company of others. When you're devoted to loving someone else, whether it's in the form of friendship, filial duty or the (urgh, dreaded) romance, the pleasure of their company, and the atmosphere that surrounds you frees you from a sense of emptiness. To a certain extent, when you're caught up in relating to other people, you don't really have time to be caught up in your own problems, or feel dissatisfied with yourself. Even when employed in a negative way, hatred of someone can be so all-consuming that you can lose sight of your own problems. I speculate that extroverts would tend to find this way of finding fulfillment more natural and possibly more satisfying.
On the other hand, being fulfilled through setting your own goals involves being single-minded and focused. Although you may not be able to spend as much time enjoying the company of others, you certainly don't waste as much time (ever notice how spending time with others tends to make you waste so much time, pretty often doing nothing much other than waiting around?). For me, one of the consolations of a more self-directed lifestyle is that it is, to a certain extent, less of a risky venture in terms of end pay-off. I can always say to myself, 'Well, even if I haven't had much time with friends this time round, at least I've accomplished such and such.'
