O the mistakes I have made over the last decade of bowhunting (Decade!!!?? Am I that old already??) Any way, here are a few of mine:

Hitting the top rail of my ladder stand with the limb of my bow, during the shot. Cracked the limbs of my Golden Eagle Sparrowhawk. I was 12 and too short to clear the railing.

Missed a Buck in a wide open field when i was 13 because i failed to judge the distance correctly. shot for 15 when he was really 25. That was Demoralizing.

Pushed a doe that was paunch shot when i was 16. This was the mistake that i regret the most. Maybe my lowest moment as a hunter. I learned this lesson well and have not lost a deer since.

These are just a few that i remember vividly. I'm sure there would be many more if I got to thinking.
