A strong desire to become a surgeon. This is very important. Do not even think of pursuing surgery as a career if you are still in any measure unsure about your decision. Perseverance. Embarking a career that will require formal studies of 10 years or longer will stretch and strengthen your ability to persevere. The ability to work under pressure. The ability to handle crises. The ability to work hard, and for long hours continuously. The ability to keep your concentration for extended periods of time. A fair amount of physical dexterity. Dexterity is an acquired skill – although only to a certain extent. If you have 5 thumbs on each hand, do not hope to become a micro-surgeon! You need to like working with your mind and your hands. You need to like working with people. Respect for the human body and for human life. If you are a medical student you need to love anatomy. A thorough knowledge of anatomy is the foundation of surgery. Intelligence. If you really struggle with your studies despite putting in effort daily, you may benefit from submitting yourself for psychological assessment to ascertain if you have the intellectual ability to become a doctor or a surgeon.

i heard a nice quote about being a surgeon, it sounds like this: The surgeon is the only artist who can actually talk to his artwork!
