Woodrow88,
Depending if your in a tree stand the guys have answered your question and fletchdp is correct about eyes. Don't make direct eye contact.
My 2 cents if your hunting on the ground is to get a few tips from:

You don't have to do everything in there to be successful, just pick out pointers that you can use.
Good luck
