Learning to snowboard is all about confidence. You can either stay at the stage where you are at for another year if you have no confidence, or you can begin to shred in a week with confidence. YOU WILL FALL, you will get hurt, but it is all a learning progress. You learn your style, what to do and what not to do. You will be scared once you take it to the next notch, just go for it.
And if you are not taking a lesson, try to do the exact same as a good boarder (How I learned).
