Crap. I'm such an idiot. What am i getting so insecure about? You're not the first person to have gone through this before. You certainly won't be the last.
Just because you've read the glowing reviews of past candidates doesn't mean that you're in any way inferior to them. It doesn't take any weight away from whatever testimony you've heard about yourself. It doesn't detract from your achievement. It doesn't allow you to make anyone else worry.
Or are you just letting it all get to you, the fact that someone else had done it all before you did? Didn't you say that it didn't matter? Didn't you pride yourself on being incredibly open-minded and liberal?
Gosh dude, you're really full of hypocrisy. You're a fake. You're just pretending to be good, trying so hard to be good, without ever truly being good.
It's time to wake up your idea man.
