Where does "want" come from? Pretty sure that's mental. And what happens when you "don't" want to be out there? When you force yourself to keep going when you don't want to.......that's mental too.
Not gonna quit and try to glamorize it as a tough mental game when i was more worried about my wife, kids, job, whatever than i was hunting.
If yer just gonna worry don’t go and waste the time money resources just to turn around and head out early, likely screwing over your hunting buddies, especially if you drove. That’s just messed up.
Will concede that dropping off a quarter and immediately turning around to hike 5 miles back in for another is definitely mental and physical endurance. You dont wanna but gotta.
Then the next day you go help yer buddy tag out. Yer a good buddy. You want this. Not mental - fun.
