It would appear that most people have no clue what they were called to do. I mean what is it that you would pay to get up and go do every morning including Sundays? I don't think most people know what that is and even those who know are not lucky to be doing it.
The irony of all this is that the few people who acutally know what their calling in life is and are lucky enough to actually do it as their life's work are often financially well-off because of it. If they are not stinky rich they just feel they are in the best place anybody can ever be. Their life is rich in all ways if not materially.
Of the people who know defintely what work/occupation would make them happy and totally fulfilled I wonder how many stumble upon it by sheer coincidence? How many just always knew that that was it? Does a liberal arts university education help in that or it is a diverse curriculum even from primary school? Does it have to do more with how broad one's experiences are pre adulthood?
