I have a sticker on the top of my riser facing me. On it I have written the following. This is on every bow I shoot.

Nock arrow
Attach release
Set grip hand
Set front elbow
Reach for and aquire target
Set front shoulder (low)
Breathe
Draw
Anchor
Set scapula
Commit
Execute
Aim

When I start missing or feel that I am executing poor shots, I head to a 10 yard target butt and blank bale and look at this list of my shot sequence until I can figure out what is going wrong. I can usually fix what I am doing wrong fairly quick this way.
