@Marbles hit the nail on the head. You run out of gas if you’re always trying to drive on E. I don’t know how much grit I have… but I spent 10 years of my life battling a severe autoimmune gut disease. I learned an awful lot about prayer along the way. Physical capacity was very low. And I found you can only get angry and hit the trail anyways so many times before your body stops letting you tap into that well of willpower. Now I’m in my thirties, in much better health, but I still only have very limited “wartime fuel reserves” so to speak. If I’m tired and I try to lift heavy or cover 5-6 miles with a heavy pack I can hype myself up and get hard shit done, but then that tank is empty for weeks or even months. So I try to save that for emergencies.
But getting out of bed when it’s cold on a hunt all boils down to one question for me… “Will I regret my decision come April or May when I’m itching to be chasing big game again?” Learn to be honest with yourself when answering that question, and you won’t have to answer to anyone else on your decision in the field.
