“Simply ‘making progress’—getting tasks done—in these jobs doesn’t guarantee good inner work life, either. You may have experienced the rude fact in your own job, on days (or projects) when you ended up feeling demotivated, devalued, and frustrated, even though you worked hard getting things done. That’s because, in order for the progress principle to operate, work must be meaningful to the person doing it.”
