Get in the woods!
Get a pair of binoculars and start going and watching deer. You can do this from your car even. Take a drive in the evening on country roads until you see some deer. Stop the car and watch them. Start learning what they do, where they do it, when they do it, then start trying to figure out why they do it.
Get in the woods and walk around. Pay attention to trails, tracks. Follow those and see where they go. Then you'll start to figure out why they go there. Then you'll start being able to look at an area and predict if deer will be there or not-based on the things you're learning.
There is no "easy button". It takes time and effort. Allot of time and effort. A mentor can shorten the curve.... But they can also prevent you from learning.....
EX you may find a mentor with nice land, stands set up, etc. You may go out with him this spring and help clear shooting lanes, trails, do stand maintenance etc. Then come fall you might sit in those stands and have a great year and kill some deer.
But really, all you learned was how to clear trails and maintain stands. Yes you'd also learn some hunting tactics and woodsmanship as you go. But not as much as if you get out there now and start learning.
It's the perfect time. Everything else is closed down. Time in the woods.
I also encourage finding a mentor. But don't let that be the deciding factor. Get out there and get started learning. And you'll meet people along the way.
