What helped me was getting a peep sight,you focus more on where you want to hit than seeing the whole deer,And I think a big thing is using a 3-d deer target of a big buck.the glen-gel buck is a good one.Helps you stay relaxedwhen you see the real thing focus,consentrate and think of how many times you hit your deer target at home in the kill zone,It all comes with experience,you'll make dumb mistakes we all did and still do,thats what I love about bow Hunting,You'll do fine.Good luck
