Let the deer teach you. See what the deer are doing in your area based on weather conditions. Wind seems to play a big part in what the deer around here are doing. Too windy they don't seem to move much. The bucks seem to stay on the down wind side of the woods when they are searching for does in heat. When going into your stand try to say down wind from where you think the deer are. If you know where their bedding area is, try not to disturb it if you are hunting a travel route to the feeding area. Slip in as quiet as you can.
Also, you want to look for sign like deer trails, rub lines, and scrapes. Do some scouting. Even if it is as little as drive by the field edges you will be hunting to see what time the deer are moving.
Like A11en says, hunt where the deer are. You figure that out, and your chances will be a lot better.
