If you're going to create a thing, shouldn't you first know "what it is" that you are creating before knowing "how" to create it?
So what is a "job"?
Maybe first we should examine a taxonomy of one's possible relations with the "job" thing.
(1) One may "have" a job.
(2) One may "do" the job.
(3) One may do useful, wealth-increasing work while on the "job".
(4) One may do useless or wealth-decreasing work while on the "job".
(5) One may be "proud" of one's job.
(6) One may have a IDGASOF* attitude about one's job.
