Sometimes choosing a career is easier when you learn what is involved in getting to that career. General surgery is a great field requiring a medical doctorate. This means that you will have to complete college with a bachelor’s degree as well as all of the Pre-med requirements (1 year biology, 1 year inorganic chemistry, 1 year organic chemistry + labs, physics, calculus, and biochemistry). GPA should probably be 3.5 or better (preferably >3.8). You will also have to score well on the MCAT. Once accepted to medical school, as long as you pass your classes and perform reasonably well during your four years of medical training, you can apply for a general surgery 5 year residency. Following that, you will likely apply for a 1-3 year fellowship. This career path requires 14+ years of school after high school but is very fulfilling and challenging work.
I know that all of the above may seem daunting in the tenth grade, but if you enjoy helping people, solving problems, and working with your hands, surgery is a great field. You'll get through all the schooling in the same way you would eat an elephant-- one bite at a time.
