So having pride in an accomplishment, for example, is a sin?
You're not having pride in an actual accomplishment, dear. You're having pride in something you imagine to be the case, based on no evidence and no actual effort on your part at all.
That would be a big part of the problem.
Wtf are you even talking about?
Is gibberish your way of conceding the point?
Your lack of reading comprehension does not indicate a problem with what you're having trouble comprehending.
Let me dumb it down for you.
You haven't accomplished anything. You're proud of how much "smarter" you are than other people, without actually being smarter than anyone at all and without ever doing anything to change that fact.
