A few tips that are most important to me are...
Obsess about your scent prevention.
Know the land more than you know your back yard.
Find the food sources, i hunt in the agricultural capital or MI so food is plentiful where i am, you just have to know when and where the deer come out and get to your ambush point undetected and your in great shape for an exciting morning/night. These spots are within sights from roads too sometimes and bucks and does always come out like clock work. Getting away from the road and people is good, but others think the same thing so even though you may think someone might be near, they might not be near at the same time if that makes sense. And if your after big bucks these spots also, most the time lead to bedding area's and staging areas so the further back on the trail you go the better chances you have at tagging one of em considering they wait up for the does to signal if things are good to go in the fields.
Might be common knowledge but it has helped me at least see deer and thats all I really care about when I'm out there, a shot is just a blessing.
Them Darned ol' deer.
