Thanks for chiming in, Budd. I see what your saying on your post and I do see the benefit to that way of training.
I will split a hair, however, and say that I think the negative connotation derived from "quit" and "failure" can leave an impint on a student that takes them down the wrong path.
It's all a matter of perspective. Had I been there and heard and seen the test committee, or participated in your training, I might have better understood what was being said. BUT...negative terminology does pay a price, example being the shodan candidate that walked away from his test twice. He was given TWO choices in his mind... and fearing the outcome of possible failure, that student chose the easier choice.
Again... I truly understand what your saying, but if it were me, I think I'd find another way to say it and avoid the negatives of "quit" and "failure." Just an opinion and nothing personal is meant or intended.
All the best!
