“It is a rule . . . in all the world that interest is to be paid on borrowed money. May I say something about interest? Interest never sleeps nor sickens nor dies; it never goes to the hospital; it works on Sundays and holidays; it never takes a vacation; it never visits nor travels . . . it has no love, no sympathy; it is as hard and soulless as a granite cliff. Once in debt, interest is your companion every minute of the day and night; you cannot shun it or slip away from it; you cannot dismiss it; it yields neither to entreaties, demands nor orders; and whenever you get in its way or cross its course or fail to meet its demands, it crushes you.”
