300 years ago when I was in high school I had a friend choose to go the HVAC trade school route instead of college. He chose the hardest school in the country where they did most things manually so that students understood how things work. It removed the "magic" some tools provide. I was pretty impressed he was wise enough to do that. He's exceptional at his job by the way.

I think we have a tendency to think the worst of your people. They frequently surprise me though.
