Hi Maria! Being a doctor is definitely interesting, even being on the path to becoming a physician is also interesting! Currently my brother is in Psychiatry, he finished medical school and is in residency. For the first year he'll be interning and currently is helping with the pandemic, however he did enjoy Psychiatry rotations during medical school. I think there are a lot of different specialities and with experience and your overall personality you will get a sense of which speciality you prefer. In your last two years of medical school (out of 4 total) you will be in electives and will be doing rotations in different specialities. That will give you an idea of what each speciality requires in addition to whether you will enjoy it or not. My sister is in surgical electives and is interested in doing surgery in the future; she likes a high paced environment and critical thinking and with many surgeons one is mostly on the move for long hours. You can also shadow different specialities which is highly recommend and even required for premed students before applying to medical school; this can give you a sense of what you like to do. For example, I like pediatrics, but volunteering in the ER I also enjoyed seeing diversity among patients and being on my feet, there is even a pediatric ER so that could be something I could do in the future. Also it could be the type of patients you'd like to work with and the specific cases, maybe oncology interests you, or working with kids or the elderly, maybe you like to be on the analytical side of medicine and not have too much interaction with actual procedures and therefore could pick radiology or pathology. There are many options but for now I would recommend to keep up your good grades and try to get experience with shadowing and volunteering (it may be difficult with COVID but keep it in mind for later on), then when you are in medical school you will get a better sense of which speciality you prefer. I hope this helps!
Best of luck!
