Those are good points about lack of caring about shooting ability being a reason not to and also that an excitable or emotional person will have difficulty.

If you get emotional about whether the animal is going to move as you shoot you never get to discuss when to break the shot. It isn't when they animal has held it's head motionless for a time and you have to count on it not moving suddenly. You have to have spent lots of time observing deer. You have to know what it does, what it will do and where it will put it's head next.

Again, that's why I posted those videos. Those fellows are right professional about it.
