RE: Let me re-phrase the "failure" question..
Looks like we just agree to not understand each other.
One thing I do want to emphasize greatly is that I hunt for a multitude of reasons, and solely killing an animal is not at the top at all. Its how I measure success, but its sure not why I hunt, or how I measure enjoyment. I trudge out into the woods many times knowing the actual chancesof me shooting something are so small, but yet I maintain that eager anticipation of the hunt and what I may experience while out there.
What ever your reasons for getting out there, or however you measure "success" good luck in achieving it.
