fear of flying/ falling

Am I really afraid of failure or of success?

I just did a review thing for grad school. It's one of those things that you aren't sure if it's a big deal or not, but you have an impact on something that's going on in someone's career right now. It's a stressful, horrible feeling for three reasons:
1, you don't want to sound stupid
2, you don't want to screw them over, but at the same time, you want to do what you should
3, you look at some of their mistakes and think "I could have done better than that"

It's one and three that are causing me anxiety now.  Number 3 because, why haven't I yet? and then you realize that number 1 is part of the reason.

I don't like being scared.
I don't like being a novice at things and my dalliance into three new things that scare me this year is more or less exploding in all sorts of ridiculous ways.
I'm trying to get comfortable with sticky situations and to get through gracephully. I'm barely getting through breathing.

I'm only making one New Year's resolution this year. It's going to have something to do with finishing what I start without complaining. I'll let you know how I wind up wording it...
