As a leader, a nurse must both be able and willing to work hard. He/she should bring both enthusiasm and proficiency to her assigned tasks, not only for the sake of the task itself but for the benefit of those around her. Positive energy that a nurse brings to work can be infectious, meaning it can have a positive effect on both the patients and the other members in the nursing team. In this connection, a truly profess ional nurse is one who is able to temporarily set aside her own concerns and problems and ill feelings while at work be cause she wants to devote full attention to the patients who look to her to provide care in their time of illne ss. As a leader, he/she always reserves a smile for all her patients no matter what her prob lems.
