The interviewer wants to know what it is beside a paycheck that motivates you to come to work every day. Talk about something that gets you excited about the job that is not monetary but rather is something satisfactory.

"I really like coming to work because all of the physicians and supervisors that I work for emphasize the quality of patient care over quantity of patients seen for that week or day. They always encourage me to take my time and learn my patients so that I can provide the best treatment options for them. This is the kind of environment I thrive in. Because they are so open and understanding I feel that I put in more time at work - not because that is what's expected but rewarded in a positive manner."
