When you are trying to describe a conceited person (not that I am encouraging this as that would be gossiping...) if you dig deep enough you realize that that person is overconfident. However, if you dig deeper, you could see that they are actually really insecure. The same things that made them seem confident in the first place could also make them seem insecure. Let me give an example.
Ok, for the sake of this whatever-it-is, let's say that this person wears very nice clothes. Now this could be an insecurity and it could mean nothing at all. It could just mean that they like (and can afford! haha) nice clothes.
So if they can afford nice clothes, that probably means that they have some money. This may be something that can give them a confidence boost. (In which case it would be a CAUSE of conceit, not an EFFECT).
Now say that this person is very athletic and good at their sport(s). This could also be a cause of conceit. The effect would be that they would show off their skills. However, if they are showing off, does that mean that they are insecure and that they have to show off so that they can use peoples' reactions to define them, which could, again, cause conceit. So the cycle continues.
Ok. Now it's getting confusing.. Allow me to confuse you just a little bit more.
This person has many friends, which is another thing that could potentially be a cause for conceit. Now going back to their clothes, could it be possible that the reason they wear these clothes is to impress their many friends? Now this of course depends on the type of friends the person has, but let's just say that yes, this is possible. Which could mean that this person uses their clothes to define them, which would be an insecurity. Because, honestly, a person who is secure and confident doesn't really care about the clothes they wear anyway. But not all the time.
Ok, so this person's general appearance is very nice to look at, not just because of their clothes but because of his/her face/hair, etc. This person is very attractive. Now let's say it's a girl. All the guys like this girl. This could make the person conceited, but it could also make the person feel insecure, as if she has to put on a show for all of them.
I did research on self-esteem for a school project, and I learned that there are three classifications of people with low self-esteem. One of the classifications is known for their fear of failure. Now this person seems to me like they could potentially be very afraid of this. Their many gifts and securities could end up as a liability.
Now, this isn't all of the examples, but going off of this, what do you think? Is there really a conceited person out there? Or are they all really insecure? I suppose it's possible that there could be, but they have so many ironic liabilities, that even if they were, there's no guarantee they could ever stay like that. They're too vulnerable! I don't know. I seriously confused my self and I probably just confused you now too! But comment! Tell me what you think!
