I think there’s a distinction to be made between “dedication” and “calling”. Regardless of one’s calling, one may or may not dedicate one’s self to a profession. So, while I see “dedication as someone’s efforts within a career field, I see one’s “calling” as a motivator toward a career field. You know Peter, there are many who believe physicians pursue private practice because they seek the financial rather than the altruist returns that come from helping patients. On the flipside, those who practice in a scheduled pay environment (like the VA) usually forego a huge financial return in order to serve some greater good.
