Its All About Me

So I have a hard time with reacting negatively with a lot of stuff, like negative comments or remarks about a lot. I have a hard time seeing the point in a lot so I just make a rude comment. Ill nod my head at you and look you strait in the eye and lie to you that I understand and I'm going to do it. But in my head I've decided that I don't like your idea and I'm going to do it my way and you can go eat some dirt for all I care. my mind is set to do what I want my way, and don't you know "its all about me." Sometimes it takes a lot to get out of this thinking habit but its hard and it takes a lot to make me realize I'm being selfish or rude. sometimes it just takes my dad to make a sarcastic comment "its all about you isn't it" or I've had friends and couple times random people tell me. I don't like being this way and i try to be more open minded about things, I would tend to be closed minded about it. I'm not really good with letting others make suggestions when i like mine perfectly fine. I was wondering if anybody else felt the way i did. Its quite annoying.
