“I was also curious why you believe being a doctor wouldn’t be satisfying for me. I’ve started to have different thoughts about medicine as well.”
I just think a doctor faces so much pressure to be decisive and authoritative, to have a manner in interacting with patients and staff, to be socially dominant, to know everything in an encyclopedic fashion–to be confident and not second-guess yourself. Yes, these are stereotypes, and it’s also true that there are many possible career paths for an MD, but I think the most common paths could be hell for an introvert. I’m not an MD, though, so you will definitely want to get a second opinion on this. It could be very satisfying, but maybe not.
Human biology is definitely fascinating, but you don’t have to be an MD to study biology and to help patients. You can broadly participate in medicine/healthcare in any number of ways. The following is, in very many ways, an unfair statement, but an MD treating a patient can be likened to an auto mechanic, whereas a researcher (basic research, drug discovery research, medical device design, etc) can be likened to a mechanical engineer/designer. The MD interacts with the patient, but is powerless without the tools (drugs, pioneering surgical procedures, diagnostic tools, clinical trial results, gene therapy tools-in the near future, data analysis, etc) that so many other people create for the MD to use.
One more thing: You don’t have to be a bio major to apply to med school. As long as you take the required courses (which you are on the path to completing) you can major in something entirely different. Apparently this can be seen as a plus by medschool admissions committees (again, you will want to consult other sources on this to verify). So you could major in public health or cognitive science and still apply to med school, while also preparing for other possible career paths. Not that there’s anything wrong with molecular/cell biology…
