Ryan,

I envy your students. I had (1) good teacher that I actually trusted what he said, and many others that B.S.'ed their way through the class or even on the job training.

Learning the NEC right the first time is priceless (to borrow from the MC commercial).
My biggest obsticle in this trade is having to relearn the right way to do stuff because I was taught wrong. It seems like the first way you learn something is the one that sticks with you. And sometimes I've, learned.... no relearned............ no this is the way it's supposed to be done...... wait... what am I doing??.....get that book AGAIN.

They will never know the headache you are saving them.
