when i was living with my parents (up to 9 yrs old) I tried to watch my father working, but he always chased me out of his shop. I learned about working from a much loved uncle. That was farm work, but i loved it. When I went into high school, i learned about accuracy from my shop teacher. He would say, "There is no such thing as gud enuf. Its gotta be purfic." Later, I got involved with a mason who taught me how to take pains to do fine work with my hands. When i first started laying bricks, he would stand over me and yell at me until i got it right.
As I moved out further into the world of construction, while still learning, i met up with an old German mason who would say, "Vell, dat vas alriight, butd, dis vay vuda been bedder." I learned from that old man. There are many ways to make job come out right. When my son was growing up, he loved working with me. He must have learned something and liked what he learned. his toys are bigger and his jobs are far reaching beyond anything i was able to teach him. I often, when I put him onto something he had never done, would tell him what I wanted how to do it and leave him while i went to do something else. About two hours later, i would come back and inspect. if the job wasn't right to my own specifications, i would tell him to tear it apart and start over. I would work with him as i showed him where he was in error and for the second time arond, i would stick with him until he got it right. He now is teaching others in a large crew how to "get it right".
I'm with Peter. A little harsh attention to detail doesn't hurt. BTW, all of the methods above work because they arrive at the same conclusion. A S4S board.
