I want to learn to not be so hard on myself for making a mistake. I work so hard to be perfect at something, when the reality is is that I'm human, I'm bound to make mistakes; no one is perfect. When I make a mistake, I always tell myself that I'm obviously stupid and am not worthy enough to study further into said subject matter that I made a mistake in. Yeah, it's pretty crazy thinking.
I'm terrified of criticism, too. I hate seeing corrections on my papers, even though it's for my benefit that I learn from those corrections.
I need to stop with my OCD perfectionist nature, as it drives me to be over-emotional, and competitive when I don't even need to be. It causes me to be insanely jealous of other students, too. That's where the competitive part of me shifts into high-gear.
