Why do you want to be a doctor and not a nurse?

I saw the value of nurses during my placement in the cardiology ward. Whilst the doctors could only spend so much time with the patient, the nurses were free to interact with the patient and were in a better position to fully cater to the patient's needs. This really showed me the importance of a multidisciplinary team - however, every team needs different roles in it. I think that whilst nurses are crucial parts of the team, being a doctor would better suit my qualities. Making more of the decisions and being more academic has always appealed to me, and this would more suit being a doctor than a nurse.
