For some, it is sitting in a cubicle, answering the phone. For others, it's caring for a young child. Or hammering boards together, or cooking, or flying an airplane.
Work is the business of life.
We all do it, whether we collect a paycheck or not. It is what keeps us alive, and what moves us forward. There is no menial work. It is all important. In all work, there is the potential for fulfillment, because there is the opportunity to make a difference.
