I always feel stupid giving advice since I've been married, what, a year? I can say this: Be in it for the long haul and just know there are going to be rough patches. No two people are the same, there are going to be areas where you just don't click.
Actually, I feel music becoming more and more important. It's a big source of inspiration. With what's going on in the world, we feel almost desperate. Music also brings you peace.
