Our jobs define us, for better or worse. When we’re out at a party and someone asks “What do you do?” we don’t talk about our love of Eastern European history or our kite-flying or the workout regimen we’ve recently put together. We talk about how we make money – our job, our work – probably because it’s only natural to focus on the activities that allow us to eat, have a roof over our heads, and stay relatively clothed. But it’s also because work is the single biggest time sucker in our lives. The average American adult with kids and a job spends nearly 9 hours per day engaged in work-related activities, more than time spent sleep, leisure, or eating.
