In Dickens' A Christmas Carol, when the ghost of Jacob Marley bewails his wasted life, Scrooge says:

“But you were always a good man of business, Jacob.”

“Business!” cried the Ghost, wringing his hands again. “Mankind was my business. The common welfare was my business; charity, mercy, forebearance, and benevolence were, all, my business. The dealings of my trade were but a drop of water in the comprehensive ocean of my business!”

- Charles Dickens, A Christmas Carol (1976, p. 21).
