When one makes a commitment, it’s usually a good idea to keep it. And it helps to brush up on a few simple tips, even for those of us who are happily hitched.

Take “15 Ways to Stay Married for 15 Years.” This list first appeared on writer Lydia Netzer’s personal blog, Shine Shine Shine, and went viral in May. Netzer, whose first novel comes out next month, renders her advice in tasty bites that go down smoothly. But they’re super-fortified, too.

Her commonsense approach is as entertaining as it is wise: “The old maxim that you shouldn’t go to bed mad is stupid,” “Don’t [mess] around with a ‘harmless flirtation,’” “Be proud and brag. It will mean everything. You will stay married forever.”

While you may not agree with every point (I don’t), “15 Ways” is a refreshing read, and wholly optimistic. “Trust that person. Love them completely and let them love you,” she writes. If your marriage is troubled, take heart. If it’s not, then hand it over.
