Although I’ve been a baseball fan all my life, I had never done any sports reporting, never interviewed a professional athlete. Strictly, I had no credentials; any of the men I approached with my notebook—managers, coaches, players, umpires, scouts—could have asked, “What else have you written about baseball?” But nobody did. They didn’t ask because I had another kind of credential: sincerity. It was obvious to those men that I really wanted to know how they did their work. Remember this when you enter new territory and need a shot of confidence. Your best credential is yourself.
