Don't take it too seriously. Sometimes you can over try. If it is a slow day, I sit down and take a nap. Don't forget luck. The last five deer I have shot were bucks. Two were button bucks and one was a large bodied deer that had dropped it's antlers during doe season. I am starting to feel weird, like I can't shoot a doe if I want to. Luck plays a major role. Scent? Bah, humbug. I have had deer walk up to me at 10 feet or less with a cigarette (before I quit) burning and a cup of coffee steaming on a log. I like to get comfortable against a log and doze off. You spread a lot less scent staying low on the ground than up a tree. Trust me on that, I used a lot of scents when I trapped. It also depends what season you are hunting in and if you are hunting public land. Just enjoy yourself and don't worry about what others do. The fun is in the learning.
