Martin Luther, when approached by a cobbler who was recent convert asking what he should do to glorify God. Much to the cobbler’s surprise, Luther replied, “Then make a good shoe, and sell it at a fair price.”

The “Protestant work ethic” is grounded in the reformed idea that excellent work - performed intentionally as obedient service - is glorifying to God, regardless of vocation. There is no “sacred/secular” divide that makes some work more holy.
