What makes this concept particularly difficult for many doctors to understand is that the bulk of their work consists of telling other people what's wrong and how to fix it. The mere suggestion that a doctor become a patient was met with a cold and hostile silence. Because physicians don't like being told to heal themselves. Doctors are human. Human beings make mistakes.
Doctors make mistakes all the time.
But many doctors have become so resistant to criticism that it becomes hard for them to acknowledge their mistakes and change their behavior. That's where a peculiar professional handicap comes into play. Children learn how to beg, borrow, and steal at an early age. They also learn how to lie and bully other people. Once they have achieved a certain amount of success with such techniques, they take great pleasure in wielding their power over others.
