Wife..just an idea. You just might want to go to a local archery shop with a shooting range and have them watch you shoot so they can pick up any flaws in your shooting form. Contrary to the popular phrase you quoted, practice does not make perfect. PERFECT PRACTICE makes perfect. Practice doing something incorrectly will ingrain bad habits that are hard to break.
I'm happy to see women getting involved in the shooting and hunting sport. It really helps our cause against the antis.
