I am sorry PF.
I know you were just trying to point out the peculiarity of feeling supreme yet knowing your own flaws. I suffer from that same thing.
You were making light of it. It's something you think about often, but never get the chance to speak of.
Truth is, you are better than loads of people - because there are plenty of awful people in the world. That's where the feeling starts.
Just be grateful you share both traits. If you didn't have the self doubt, you'd be an asshole. And if you didn't have the confidence, you'd be dead.
If none of that applies to you, I guess I'm just talkin' to myself.
EDIT: I am sorry this thread turned out like this.
