"It's not the lack of love, but the lack of friendship that makes many marriages unhappy."
— Friedrich Nietzsche
The power of friendship in a relationship can't be overestimated. You may know you can rely on your partner for anything, but it's important to like each other, too. So put the same amount of effort into your spouse as you give to your friends — funny e-mails, impromptu dinners, all of it.
