Yea,for a new shooter there is a lot of shot sequence parts to think about.Just stay close to your target 5-10 yards for now and try to concentrate on one part.Don't even worry about aiming,just work on that one part untill it becomes automatic.Then work on another part.When you get all the parts down then start aiming.
A very fine shooter finally got it through to me that the worst enemy to a great shot is trying to think about hand placement,back tension,proper anchor,follow through,or anything else when you should be aiming in total concentration on the spot you want to hit.
