RE: Starting out.
Shoot close starting out and don't be afraid to use a prealignment method. I recommend this in preference to sights for developing an instinctive method because it forces you to maintain the alignment at full draw without further reference to the arrow.
Don't overbow yourself. You can't develop good technique if you can't reliably find your anchor under your dominant eye. Also pay attention to keeping the bowarm firm and pushing at the target so you can get a good consistent stretch on each shot.
Take your time. Rome wasn't plundered in a day. And don't give up. Plenty have but quite a few manage to get there no matter what. The difference is persistence.
Also, remember, once the bow's tuned to the arrows, whatever's wrong ain't the bow and whatever's right is you so work on tuning you whenever possible and leave the tinkering to the compounders.
