Yeah, gonna pull the NTR card. Who ever understood something better before they did it?
I've had to teach physical tasks to innumerable people of presumably every type and I never really noticed any that held my words particularly more highly than actual practice. Kinda wish some had, but I'm not sure if they disregarded them or I just wasn't able to transmit the central principles of building brick walls out of boxes. Generally, it's better to show as you explain, walk them through not just the aspects of construction but the way you move, what you look at and look for, sort of the cognitive experience of looking back and seeing a hundred boxes coming down the chute and trying to find the most common dimension and basing each shelf on that, bending at the knees not your back and grabbing each box by opposite corners, giving it a quick spin to find which side the label's on, scan, pivot back to the wall, place, deep even breaths, pivot back, push flow while looking for small boxes to fill inevitable odd holes, intensity, break jams, hydrate, help others, hunt for backed up trailers, control your anger, smile, laugh, elevate, don't look at clocks, focus, feel the muscles you're using, delight in motion, be a dork and post this on the internet.
