Every time you go out and practice without knowing what you are doing you are reinforcing bad habits. I get the wanting to go out and put down range some lead, I really do. I spent nearly a decade doing that without knowing what I was doing. Throw in some "friends" who liked to mess with my sights when I wasn't looking and all I was doing was wasting ammo (yes they suffered for that later lol). Learning the correct grip, body position etc all the way down to how to pull the trigger, and finally, how to self diagnose are what sets apart those who merely plink and those who actually shoot. Men especially have an issue with seeking out instruction for things, our ego gets in the way and even once we have sought help, the ego makes us fight what we are being told. You don't know what you don't know, and that will hurt your ability to improve.
