I know what you mean, I hate that little fear in the back of my mind. Lately I've started listening to music, rap specifically, and it helps to get me pumped up to try new stuff. I'm also getting a helmet soon. I basically just said "fuck it" and before I had time to let the fear sink back in I was heading towards the jump. I also thought to myself after pussying out once "wow I'm all talk, I'm going to regret this if I don't try it" and so I did. In just the last four days I've tried a 3, solidly gotten them down, working on 5's, switch 1's and cork 3's.
