It is not that one has to be a genuius to learn, it really takes more steady perservering dedication to the task day to day as a priority over everything else. To survive in practice one has to join them or sink financially. I really believe Albert Schweitzer would be appalled by modern medical practice and run happily back to the rain forests of Africa. Don't get me wrong. I know many doctors have abused insurance systems and probably still do, have done harm and should have their licenses revoked by medical boards, and there should be safeguards to protect us all.
Many doctors have huge debts after finishing training and are too intent on making money.
Also, many medical marriages fail because of the physical and emotionally absent medical member. He or she is not the same is not the same person I married. I was 35 years old when I passed my board certification examination because at that time, I had to have two years of clinical experience beyond residency before I would be eligible for the exam. My written exam was in Wash. D.C. and my oral exam was in New York the following year. My wife went with me and I carried my portable ventilator to survive.
