Dr. Gary North is a successful economist and entrepreneur. He discusses the difference between job and calling.
A job puts food on the table. A calling is the most important thing you can do in which you would be most difficult to replace.
Service is the key to succeeding in a job and a calling.
According to Common Sense Economics, if you want to earn a high income you must get really good at something people highly value.
In terms of a calling, the greater the service the greater the calling.
