I was working in the same building as U.S. News & World Report, and I banged on the door and said, "I'm ready to go." And they said, "What's your combat experience?" I said, "Does my parents' divorce count? It was pretty rough." Then they said, "What's your reporting experience?" And I said, "I covered the women's volleyball team in college exceptionally well." The guy was like, "You are so not ready to be a war correspondent."

Then you meet the right guy, and you're not in list-making mode; you're just with the person you're supposed to be with. Jobs are like that too.
