This is what someone who has already been through med. school had to say about the profession I want to go into:

     “These were people-mostly men- who ate determination for breakfast.  They had no use for the slow, the sensitive, the theoretical, or the timid. They thrived on stress and sleeplessness, they were openly proud of their ability to take punishment, and they enjoyed making moment-to-moment, even snap decisions quickly, and they expected to be right.  Last but not least, they acted-in the operating room, in the Emergency Ward, on the recovery wards, and in the outpatient clinics, every hour of every day in every way.  This was their reputation, and this was the impression I was to carry away from two months with them.  For the present, I was frightened as well as excited.”
