I found it interesting to learn the etymology of vocation ("vocatio"). I have sensed this calling in some sense, from my own thoughts to praise from friends and family.
Many of the students I see around me, and even myself, have a lack of knowledge about the past, are apathetic about the present, and do not care enough about the future. A facebook status update will not change the world. But will a drawing? A painting? Traditional art has certainly been lost among the myriad distractions, but that doesn't mean all art is lost and nothing is getting through.
