No worries, I missed my first 6 or so whitetails the first year I hunted (hit a plate every shot at 40 yards but couldn't hit the broad side of a moose at 10!!!). Don't be so anxious to lose that excitement. I wish I still got that nervous feeling but now after 20+ years of it, I've got to the "stone cold killer" point that my heart rate doesn't even fluctuate (I think it's a survival trait necessary for throwing sticks at really big bears, but I miss it.)
