Secret to a Successful Marriage

From Michael Ian Black:

"People ask me all the time what the secret is to a successful marriage. I compare a marriage to running a marathon. There are many times during the course of a marathon when you feel like you can't possibly go another step, when you feel as though you would rather die than continue running. When those moments come, just tell your body "one more step." Just one more step, and then when that step comes, no matter how excrutiating, no matter how much that tiny step makes you want to vomit, tell yourself, "Just one more step." And then you keep doing that until one of you dies. That's the secret."
