This may well be true for some, or even most kids, but I know it wouldn't have worked that way with me. If I'd gone to someone else's honey hole and shot a big deer sitting in their stand when I was 10 it would've substantially reduced my drive to go more and get better. There's certainly nothing wrong with your first deer being a random hoss, but there's obviously something to be said for the self discipline learned and the memories of the time and work it took to find and kill a big deer. If you make it too easy it's liable to cheapen the whole experience for a child whose opinions on hunting are still being formed.
