"I am successful as an administrator because I genuinely care. My work is my career, and not just a job, to me. I care about my company, my boss, my coworkers, and the clients that walk through our doors. In addition to that, I genuinely care that the work I deliver is top-notch."

You can bring in a little bit of your personal life into the answer. Perhaps you are successful because you have a never-ending curiosity and you spend a lot of time researching the industry in which you work. Maybe you read a lot of business books or listen to podcasts on your way to work. Perhaps you take part in activities that offer you a definite mind-shift, like yoga and meditation, which allow you to give your best at work and be uber-focused. Share with the interviewer the ways that you ensure you are successful in your career.

"The secret to my success as an administrator is my ability to earn rapport with clients, over the phone, very quickly. When someone feels comfortable with you immediately, you can almost guarantee that they will become a repeat client. For this reason, I often have customers telling my boss how lovely it is to speak with me. It makes me feel good, and this appreciation goes a long way in fueling my fire to be better every single day."
