“Actually, the relation of a person’s vocation to his or her paying job can be quite varied and will change over a lifetime. Sometimes your job is just the way to make money; the vocation is pursued in your spare time. A fine example is Einstein’s developing the theory of relativity while he was a clerk in a patent office, happy to have mindless work so he could be free to think about what mattered to him. At other times, we can find or create a job that fulfills our vocation, and the pay will be at least adequate. There may be many possible jobs that do that, or the job that will serve the purpose will change as experience grows and the vocation deepens.”
