“If you ask me what I came to do in this world, I, an artist, will answer you: I am here to live out loud.” ― Émile Zola
So far as I know, the notion that we might have a calling in life is derived from the Christian notion that some of us are called upon (by God) to serve God, perhaps in the role of a priest or a friar. That notion, as it developed, became remarkable for how opposed it was to the Medieval notion that we have only to play out the social roles we were born into.
A peasant's duty was to be the best peasant possible. A nobleman's duty was to be the best nobleman possible.
The Christian notion, which is now secularized, has become a notion that each of us might have some individual calling that over-rules what class we're born into, and might even over-rule one's economic interests. Van Gogh:
“Your profession is not what brings home your weekly paycheck, your profession is what you're put here on earth to do, with such passion and such intensity that it becomes spiritual in calling.”
As for myself, if I ever were to feel a calling in life, it might have something to do with counseling folks who seek my counsel. Not teaching, as you might suppose. I once thought I might enjoy being a professor, but I was wholly disabused of that notion decades ago when I got a job tutoring university students in logic. Oh gods! But I did suck at it! I was completely unprepared for how apathetic I would be, excepting only those students who were totally enthusiastic to learn.
Yet, counseling is a different thing to me in so far as it involves now and then both solving the sorts of problems I most like to solve, and then seeing someone actually apply my solution to their problem successfully.
Beyond that, I suppose my most heart felt calling is my personal spiritual journey -- by "spiritual", I mean the manner and extent to which I am able to deal with or manage my psychological self. aka "ego".
Last, it should be obvious, I think, that following a calling can be a means to being true to yourself.
Do you feel you have a calling in life? If so, what is it? Do you see it as something you passionately embrace, or more as a burden imposed upon you by something?
Do you feel your calling is leading you to self-fulfillment?
