Tim McGraw joked with us in August that his No. 1 goal was to remember his upcoming anniversary to wife Faith Hill. The couple celebrate 20 years together on Oct. 6, and the "How I'll Always Be" signer has wisdom to share after two decades of wedded bliss.

Lesson No. 1: Listen. McGraw jokes that as a guy living with four women (he has three daughters), he really has no choice but to listen, but gets serious in talking about how important that is to a strong marriage.

“And I’ve also learned," he adds, "that when you look at politics and you look at the world we live in and everything else, there’s really no definite answers to anything. There’s a lot of sort of figuring your way out with every move that you make. I think that you find that out as you get older and that really has to do with relationships, as well.”

McGraw and Hill have done well raising three daughters. The oldest, Gracie, is at Belmont, while their middle child is just beginning college and the youngest, Audrey, is preparing to start high school. None of them are ever very far from home, however, so McGraw often has to remember an important rule.

“I don’t really have a lot of say-so at my house," he assures.

McGraw famously proposed to Hill at Country Jam in Grand Junction, Colo., in June of 1996. He asked Hill to marry him in her dressing room trailer, and she responded by writing her answer in sharpie on a mirror, adding a few lipstick kisses. The couple still have that mirror. They married on Oct. 6, 1996 and had their first daughter the next year.

McGraw talked to Taste of Country at WE Fest 2016 in Detroit Lakes, Minn. He also opened up about what his new single from Damn Country Music made him think of the first time he heard it.
