Thule, experience is going to be your greatest teacher. You might muff a few shots, spook a few deer, but hey, we've all done it and it's only bad if you didn't learn from it.
There's a great deal of knowledge to be gained from this forum and an overwhelming amount of info online and in bookstores. These guy's and gals on here will answer any questions you may have. The advice about trail marking with ribbon is great, but I would prob. suggest using a reflective tape so you can get out when it's dark.
As suggested before trails are a great place to start. If your hunting 1000 acres and are deep in the woods, chances are that if it looks like a game trail it prob. is. the leaves will be beat down pretty good, leaving no doubt. study the trail good for tracks, poop, even rubs and scrapes that might be off the trail a little. If you have a fence line crossing what appears to be a trail check the wire for deer hair. Sometimes a deers belly will graze the wire when they jump it, leaving behind white hair. I've even found white hairs on logs and trees that have fallen across a trail. This tells me that the trail is still being used frequently.
Play the wind and keep movement and noise to a minimum. When I hunt off the ground, I clear me a bare spot, free of any leaves or sticks, so deer don't hear me when I move.
Most of all, be resilient. It might take you a few outings, but the longer you do it the more proficient you will become, and your patience will be rewarded. Good luck and happy hunting!!!!
