Do it. You will never get over the fear if you don't. Not only will you feel amazing that you overcame your fear, but you'll be less nervous the next job you want. The nervousness doesn't last. Trust me, I was so scared when i came to the farm, and I just love it now. I'll be more likely to do this again sometime. Goodluck. I hope you go for it. I know you'll kick yourself later if you don't!
