There's a shift that has to occur when you go from student to doctor, from employee to employer, from worker to manager or supervisor. You've got to shift 'hats.' This is not an easy shift, since you might be so used to and so conditioned to be a student or employee or worker that switching roles is uncomfortable. To get past that, start trying on the 2nd hat while still wearing the first. Think like a doctor when you are a student. Think like an employer when you are an employee. Think like a supervisor when you are a worker. This way you are preparing yourself for the ultimate role you want. Just like the old saying, "to be, act as if!"
