Years ago, around 15 or so I reckon, I had 10 straight misses in the same season. The 11th shot found its mark on a nice 3x3. I ended up sneaking to within 8 yards of that deer, all the misses were farther. Never once did I think about giving up but I was worried because I was running out of season and didn't want to end up empty handed.
Looking back, that bow was not tuned well at all, it was also a little heavy for me. Before I got rid of it, I did manage to kill a few more mulies and a couple of elk, but I missed a lot too. I just figured all the misses was the name of the game, now a days I know better.
Tune tune tune and practice practice practice. At some point it all becomes second nature and you'll perform like a machine when the time comes.
