Perhaps because I am a veteran of the "good old days" (they were really quite bad), young physicians who hope to become clinical investigators often ask me how they might establish their careers. Many are more than a little worried about their futures and often have trouble envisioning a career path that is financially secure for themselves and their families. The grumbling of clinical investigators a few years their senior enhances their angst. So I try to encourage these young physicians because I know the great intellectual (if not monetary) rewards of the field and because I know that the future of medicine absolutely depends on clinical investigators. The following is what I try to say to them.
