You know I often think I should have apprenticed more at different places when I was in my teens. Of course in my teens I was busy chasing trouble, but had I any sense I would have chased an electrician, a plumber, an upholsterer, a sheet-rocker, an auto mechanic, and a carpenter. I'm fairly proficient in several of those at this stage of life (often through trial and error) but some serious training for a year in each would have been helpful .
