All of the most awesome people I know have nothing like a work-life ‘balance’. Instead, they work hard, play hard, and tie that to a mission bigger than themselves.

Whether that’s true for the staff on targets in Amazon warehouses is a different matter, of course. But for knowledge workers, I think it’s spot-on.
