Try some spots you've never sat before, scout and look for sign. Rubs, scrapes, poop, etc. If you find good sign, you will see deer. I'm still learning myself though. I use to look at a head of woods and say "man, this looks like a good spot for deer" and then I wouldn't see a darn thing. Don't pay attention to how good the spots look, because if there is no deer sign you can just about forget seeing deer. Hang in there man, just try to switch it up a little bit.
