Welcome, Bassmantweed!

I think we all have the jitters the first time we pick up a really sharp piece of steel that looks enormous when you put it up against the face--and then proceed to slide it down said face, sharp edge leading.

+1 to what others have said--relax (but pay attention!), take your time, and learn to use that non-dominant hand. If you're about to try something new and you don't feel comfortable, stop. You'll be surprised at how quickly you progress when you don't push it.

Good to have you on board!
