If you have been married 25 years or longer, what one piece of advice would you give to those who are just starting out?

Linda and I have been married 45 years. This week, I was reflecting on the various things that have made our marriage a success. I would say that the number one thing is that we have prayed together every day of our marriage when we have been together. I am convinced that sharing a time of prayer every day makes a marriage stronger.
