What are some ways you guys make the effort to be good wives?

I was thinking the other day and realized I read all these child psychology textbooks and have an entire binder full of parenting notes from seminars I’ve attended, yet it has never crossed my mind to put in the same effort to my marriage. I love my husband, and honestly it’s always just come naturally to us to get along. We are best friends and lovers, we fight, and then it goes back to normal. But I know that if we get out of autopilot, it could be even better. What are some ways you make the effort in your marriage?
