More importantly, you must decide if medicine is a field that is right for the kind of person you are. I believe that there are three cornerstones of a successful career in medicine:
As a physician you have an opportunity to help others. Wanting to help others and enjoying helping others are necessary attributes of a good physician. This is something that cannot be taught. However, there are many other professions that can help others. Politicians, religious leaders and social workers all have the opportunity to help others, perhaps in larger numbers.
Medicine is a career filled with choices. In what other career can you choose between delivering babies, taking care of children, handling emergencies, removing someone's cancer, or talking to someone who needs psychiatric help? Better yet, you can teach others any of these specialties, and while teaching have the opportunity to both practice your profession and teach it. Alternately, you can do research in whatever specialty you choose, with the potential to make a real breakthrough in preventing or treating illness. In addition medicine is a career that is honorable and is held in high esteem, allows you the ability to live just about anywhere, and provides job security (unfortunately, illness is something that will be around for the foreseeable future).
However, all of this comes at a price. The many years of preparation, the discipline, the awesome responsibility, the worry about malpractice and the long hours can take their toll. Medicine is a unique field and it demands a unique person.
One word about money. Please don't let this be a driving factor in your decision, for the sake of your patients and yourself, because it will not sustain you. There are other careers in which you can make more money without the responsibility and the effort it takes to be a physician.
