What is it you do?
No musician can go straight in and play without having practised and made mistakes - trust me I was a music teacher If you don't try then you'll never know if you can play it. Go, play a couple of notes, next time play 1 more.... You'll be playing phrases and pieces before too long. But if you don't make mistakes you're never going to learn or have something to compare to.
