I haven't heard the 'work hard, play hard' motto for a while. I remember hearing it all the time back in the early 2010s. The 'work hard play hard' mentality seems to be a relics of the hustle culture. I've no idea where it came from initially but our kids started to watch the original Teenage Mutant Ninja Turtles TV show from 1987 and while I was re-discovering the intro -and esp. Michelangelo's line- I wondered: was it a first inception of the 'work hard, play hard' lifestyle? Or in their case: 'save the world, play hard'.
