Ok, so it seems like this application has turned into people saying that I am immature, and you're not wrong. The main thing though is the reason I act immature; I am always on full damage control mode unless things are going well. That's why I "solved immaturity with a gag", because I think in the moment "Hey, if people laugh, they will forget about this immature thing that I did", but that seems to only work with the poeple I am used to dealing with, people my age with my maturity level.
I am running out of ways to justify my prior and current immaturity, so unless I am asked a question that I can realistically answer, I am going to stop responding as much.
Another thing I do if faced with a lot of criticism is self deprecation, which is also kind of what I am doing at the moment, but I don't know how else to respond. I would like to say, though, that what I might lack in overall maturity, I make up for with actually completing the task I am given and being able to do so.
This kind of post may either help or hurt my chances with this, since it can be seen at 2 different angles. If anyone else has any questions or comments, please post them, and I'll try to respond as best I can.
