RE: Let me re-phrase the "failure" question..
I set objectives at the start of each season and each hunt, whatever the objectives may be.
But you asked specifically about a "season" so I will stick with that.
I have started seasons where my main objective was to get a kid or newer hunter their best opportunity to harvest an animal. I have passed on my own opportunities to see the kids prosper.
So in that situation it could possibly be called a "failure" for me and a "success" for the kid or newer hunter. But I would of course consider it a personal success because I obtained my objective and in the end I could certainly smile bigger than if only I had harvested an animal.
