Well all those misses mean is that you didn't get to put any meat in the freezer, but the biggest story, it says you just need to get out there a bit more and practice hard like you do with that bow. You'll get there! Just takes practice and a cool clear head to get the job done.
As you said, when that smoke bellows out and fills the air around you and you get to start looking for blood and then finally the animal down in the brush, its a thrill of a lifetime! Good luck to you next time out.
