In the competitive, industrial or post-industrial world, productivity is often defined by a simple formula: Output / Input. (Output is ideal output x efficiency). Or Value of Work / Hours Worked. You have metrics like revenue per employee, revenue per hour, and units produced per hour. From this angle, productivity seems more fitting for machines. But there’s a more positive aspect that is not easily measured. Productivity means being engaged in doing the things you really want to do and doing them really well. It means being empowered to design a well-lived life, which sparks big memories out of tiny moments.
