There is something to be said for the fact that surgeons like cutting on people. Or whatever procedures it is that they do. It can vary sooooooo much.
Inserting a cochlear implant is surgery; so is removing a colon. They are very different procedures.
That said, just learn anatomy for now. Besides anatomy, do you like working with your hands? Like, a lot? That matters.
What is often said, and was true for me, is that many people know the first day they are in the OR. Not the anatomy lab mind you, the *OR*.
I like butchering whole chickens, I loved anatomy lab, like to build things out of wood, embroider, etc. But I knew the first day I was in the OR that it wasn't for me. I tried to keep an open mind during my surgery clerkship. I was fascinated by everything taking place, but the OR was not where I wanted to be long term.
Surgery is something that can really choose some people, and it can really unchoose you. Thinker vs cutter distinction can happen easily for most. So don't stress.
And if it doesn't choose you/immediately turn you off right away, still don't stress. Lots of time and experiences and hours stand before you, and mentorship, to sort it out.
Also, it's natural to wonder all this at the start. We all did!
