They have a natural tendency to emulate what they see. If there is a respectable example around them, they will want to emulate. Maybe that carving class teacher was a realy cool dude.
Most important is to not stifle the passions that the children have naturally. My parent were this type. Constant nagging. "You spend too much time at your computer! You should be more like this other kid that plays sport!" or "Isn't that book too smart for you?" So I learned to hide my interests from them.
