first take it to a pro shop and have it checked to make sure it fits you right. Likely the draw lenth is not set right for you. Second shoot it, shoot it, shoot it, and when you think your good to go shoot it from a stand. With bow hunting you have to get close, scent control is worth a million when you get that buck in range and he smells you and makes a run for the thickets. I am anal about it and was not when I gun hunted, though also new hunter like your self. I have been at it 7 years this season with this being my 4th bow hunting and have not killed a deer. SO do not get upset if you miss out this year.
Welcome to the sport and remember shoot shoot shoot.
