I'm the same way with hunting. Actually I'm the same way with everything. Check. Double-check. Triple-check. And I use to haul along way more gear than I needed...just in case. And forget sleeping the night before. I'm a 51 year old hyper kid waiting for Christmas morning.
I've been eye-balling a fat doe eating the clover I frost-seeded in the spring. It's like lush pillows of green right now and deer are eating and bedding right in the clover. The doe is safe in the yard but I suspect I'll see her near the back of the 40 where I have another small clover plot for hunting. I did a brief article about it if you're interested http://deerfever.com/2015/08/inexpensiv ... t-options/
There's a small buck, and couple other does, and some yearling coming around. They don't even bother running away anymore when I walk outside. No challenge to hunt them let alone shoot them.
But back to gearing up, self-sustained bike touring taught me to pack wisely and buy good quality gear. When you're on the road in the middle of nowhere everything depends on your physical condition and everything you can possibly strap to a bicycle. In comparison, packing into the woods for a hunting trip is very similar. I literally use the same essential gear for a few nights of hunting as I do for a few nights touring. So for everything from my shelter, cooking, and electronic media, I'm always organized, packed, and ready to go. No need to double check that gear. I could toss three packs into the truck right now this minute and rest assured knowing I have everything I need for a few nights in the woods except my clothes and some food. And that preparation makes a big difference for me personally.
What you do in the dark will someday come to light.
