The definition of a doctor is "a person who is qualified to treat people who are ill." You might want to be a doctor because you love to help people, be of service. You want people to live life to the fullest. You want to improve people's quality of life. Give people the best chance in life. Have you watched Patch Adams? It's based on a true story. He says "You treat a disease, you win, you lose. You treat a person, I guarantee you, you'll win, no matter what the outcome. I have no clue how to answer that question, but if you watch Patch Adams, you'll have many answers. I don't know because I'm not brave enough to have life or death put into my hands.
