the blades... If you act like your pulling your bow apart, you'll tend to pull your bow hand to the left.

I shoot a thumb release for competitionand hunting. Just pull back with your release in position. if you shoot a trigger release, hold the trigger and start to pull back using your back muscles, slowly. Practice this with your eyes closed.. Get close to your target first.... It will come together.
PM me if you need more help. I'll give you a phone call.
