In an attempt to keep my sanity (lol) I break my "hunting stuff" down into categories. For instance.....there's the clothes---figure out what you need there.
Then there's the footwear-----what kind of boots do you need?
Then, tool of choice.....bow, rifle, shotgun, etc....
Scent control if needed?
ammunition....
packing equipment---backpack, pack frame, etc...
reloading----equipment, supplies
The reason that I broke it all down to you is to show you how I try to organize my stuff so that I know what to buy, take with me, or stock up on. With wondering "what to get" like you are, I'd break it down and work on one area at a time.
