All of the doctors I have spoken to expressed the following in similar terms: "if you're going into medicine for the money, you're going into the wrong profession." There is too much stress, school, and other complications to justify the pursuit of these careers monetarily. Consider instead, for example, teaching/researching in an academic setting. Most of all, if there exist reasons for your choice of a career in a medically related field, may they stem from the fact that you will thoroughly enjoy your job because of your love of the subject and its benefit to society.
