As a first time poster in this place, I'm honestly amazed by all the responses in here.
In the first place, I have to say they're all perfectly written and ellaborated and so, so easy to relate to.
It's always been somewhat of a concern for me. I consider myself to be an intelligent person; I like studying, I like learning and I
love understanding things. The problem - as everyone else's here - is that I have a hard time grasping long and winded explanations of things I don't have a reference, or previous knowledge, of.
I've analyzed myself to the point of declaring myself a 'classifier'. To understand something I need to see order and 'logic' (by this I mean my own patterns of logic) in what's being said. I need to see things by my own classifications and patterns. Generally, once I've got a classifier in my head, everything related to it directly jumps in there - meaning that I instantly understand anything that makes a reference to something I've already categorized. Personally, I've got an excellent mind for abstract things that most people struggle with.
However, when it comes to other things - mainly numbers, statistics, economics and other systems which work with a logic of their own - I have a very very hard time processing information. Rather, I take my time into creating new categories, new classifiers that can adapt that information to my sense of logic. (Generally, when in a conversation with someone, if they go on about something I do not imediatly grasp, I'll shut down for a second to process the info, order it in my head and then resume listening. Unless I simply get lost at the start, am unable to intake any more data and am only capable of sitting there making a great impression of a poker-faced hollow-headed nut)
So mainly, my problem is the same as everyone's, only that in my instinctive (and often annoying) habit of analyzing and naming things, I've come to blame it on my innane need to keep things ordered and classified. I guess this is mostly due to my natural perfectionism (enhanced by being a Virgo, if anyone believes in that~)
Also, as a last thing: sometimes I find myself in the case where, not having understood an explanation/concept/point (because I've not been able to process it as mentioned yet), I'm capable of forming a correct answer to a question about the subject. It happens often in my statistics class - I'm far behind my colleagues when it comes to understanding, yet most of the time I'm the one coming up with the correct answers to the exercises. Answers I don't even know how I came up with. It's like my mind has actually understood the concept, but is making fun of me by making me think I don't. Or something. Does this happen to anyone else?
Anyway, so much for order and classifications in my post - I probably made a mess of it for my first time here...
Regardless, I'm very glad I've been able to find this forum and the people in it. Really makes me feel so much less 'dense', as I've always felt thanks to this issue... ^^;
