We all get scared. Trying new things is scary. We may respond differently to fear and new things, but WE ALL GET SCARED. The thing is, there's no way around it, no short cuts; the only way to mastery, competence or achievement (and farther away from "new scary thing") is to do it. DO IT, DO IT, DO IT. It takes hundreds of trials and errors. That is thee process. For everyone. Why are you so special that you want to be perfect from the start, or (with hands on the hips) "I won't even try to do it" (all stubborn). Nobody gets to be perfect. Ever. Especially not at the beginning of anything. Grab onto your ovarios or cojones - whatever the good Lord gave you - both if you've got them and dare to do it. If for no other reason than to spite the Evil One that tells you that you can't or that it's impossible.
Hmm. Don't you just want to show 'em?
