For those of you who are married, what would you list as the most important things in a successful marriage?

For me, I would list it as 3 particular things equally balanced:

Love (the passion, the romance, the sex, etc.).

Friendship (the act of simply liking to hang out with that person).

and

Compatibility (being married means having a roommate which can be a challenge on its own).

What do you guys think?
