Celebrating Thirty-One Years of Marriage: Ten Things I’ve Learned and a followup by David at Ridgecrest Blog. I designate both posts as required reading for anyone who has entered, or is considering entering, into marriage.

Best points:

Forgive! Eric Segal’s characters in Love Story liked to say, “Love means never having to say you’re sorry.” What a crock! The only human being who has no reason to say they’re sorry is dead.

…

Love and take responsibility for your kids, if you have children.
Some men and women view their children as unwanted impositions, which is a tragedy. If you’re not willing to take equal responsibility for the upbringing of your children, then don’t have them. But if you are willing, they will bless you and your marriage.

And you’re not allowed to change your mind after your kids are born or adopted! They don’t go away; neither should your commitment.

10. The best gift a man can give his children - is to show them how much he loves their mother.
11. The second best gift he can give them - is his time.

Also highly recommended is Mark’s It’s Time to Dethrone Romance.
