Look around you and you’ll see three kinds of people – those who hate their work, and complain bitterly, those who just tolerate their work and see it as a paycheck and aren’t looking for more (or feel they can’t have more), and finally, those who love their work, and relish it.  The third category is a small subset of all professionals globally, but this group stands out because these are, most often, the people who change the world for the better.
