Like giant containers of volatile gas, money must be managed with great care. Because most of us don’t have more than we need, we must be wise and faithful with what we have. Our tendency in marriage, however, is to procrastinate. “Tomorrow we’ll get organized,” we lie to ourselves and our mates. Or we try to maintain an unrealistic and impractical financial system, which ultimately discourages us. No home can escape the clutches of coin and currency—so we must learn how to implement wise policies of earning, giving, spending, saving, investing, and borrowing.
