On accepting your wobble, it is one of those key pieces of advice that new shooters get a lot less value from than they should. They hear it and think "Great, I accept that I wobble, a lot! Now what?"
For me that advice translates to once I've started trigger movement I am not stopping barring something really dramatic happening such as the target blowing over or my trigger pull becoming 1000 lbs. Trying to pull through chicken finger doesn't work. I keep the sights where I want them in black but do not try to muscle the gun to perfection.
