I'm darn sure not a pro but I'll answer anyway. When I come to full draw ...

1. Check my grip
2. Put my index finger knuckle right under my ear lobe
3. Bring the string across to the center of my nose
4. Cock my head just enough to center the sight guard ring in the peep
5. Double check level
6. Concentrate on target and puuuuulllll back .... WHAACK
