I'm reading a book called, "On Earth as it is in Advertising?" by Sam Van Eman. Within the book he quotes Frederick Buechner on the idea of a calling. Buechner writes,
"The kind of work God usually calls you to do is the kind of work (a) that you need most to do and (b) that the world most needs to have done. If you really get a kick out of your work, you've presumably met requirement (a), but ifyour work is writing TV deoderant commercials, the chances are you've missed requirement (b). On the other hand, if your work is being a doctor in a leper colony, you have probably met requirement (b), but if most of the time you are bored and depressed by it, the chances are you have not only by passed (a) but probably aren't helping your patients much either.... The place God calls you to is the place where your deep gladness and the world's deep hunger meet."
