Yeah, you "understand what we are saying," but it obviously just doesn't apply to you. You have it all figured out! I mean, you were able to buy a truck! You are way ahead of the game. If you wrote a PDF on how to be awesome at life. I would have to buy it.
Seriously though, have you ever just simply said, "I see what you guys are saying, I will give it some thought." ? What is with the need to be one up on everyone? Some people, a lot of people recently actually, have been trying to give you some advice, and you brush it off as if it does not apply to you. There was an attempt to explain to you the difference between being proud of what you do, and being prideful, and you just brushed it off with a "that isn't me."
You are in for a rude awakening later on when you realize that there are those that just don't put up with things so well. You say you are a very "friendly" guy and "likeable," but what you do not understand is that High School is not a good representation of how the world works. If anything, nowadays, high school is anything but what the world is like. Just because you are like-able now, does not mean you will be that way forever. We have been trying to give you advice on that fact, because there is really good potential in your magic and in your performance ability. Why throw all that away for your, "I am holier than thou" humble arrogance act?
