“Piss off early, tomorrow’s Saturday.” A phrase I remember fondly from my time in the Armed Forces. Also, Wednesday sports afternoons were a thing, which in hindsight was a real blessing.
I recognise now that the Army, at least in my day, invested heavily in developing its people and facilitating their self-development. Not on top of the day job, but as part of it. Time was set aside, rather than pushing an individual to snatch time in between tasks. It wasn’t perfect, of course, but there was a broad and deep commitment to growth.
Rest and a little slack both help folks to move forward.
