I agree, an apprentice gunsmith starts by making the tea, sweeping up, watching the master in action, getting the bacon butties, and eventually learns all aspects of the trade from making the pins that hold the locks, through sears, hammers, springs, tumblers and firing pins, lockplates, triggers, barrels, jointing, blueing and heat treating, stocking, fitting, patterning and final finishing.

I really hope the you get to where you want to be, the country needs engineers, far more than it needs social scientists or psychologists!!
