Well only one way to find out. Make an effort to reach me on here if you feel that way many years from now.
nothing is monotonous if you care about it enough. I eat 2-3 meals per day, but as a foodie I'd hardly say that eating, even after 22 years of doing it, is monotonous considering the diversity of food I seek out/cook.
While not all fields are the same, the landscape of how medicine is practiced definitely changes with time and context. Monotonous is probably the last term I would use to describe medicine. (/day dreams about robots)
on a everyday basis there is variation from one patient relationship to another patient relationship, one case to another case, team to team etc. on a larger timescale there is variation (i.e. research) that changes how to best help your patients, asses & treat diseases etc.
its only when you treat your patients in a "monotonous way" that you can achieve that feeling. - and i'd say that feeling coincides with complacent sh*tty doctors who can't be bothered to keep up with the newest advances in the field or always treat their patients algorithmically. You might as well become a NP if thats the case and you don't want to engage in critical thinking for each and every patient.
I had this converstaion about monotony with my PI who has been in the same field for 3+ decades. Paraphrasing her, the entire point of entering a field with a scientific basis/foundation is that you get to be objective about your own successes/failures, those of others, and continually refine the lens that you view your work through.
but you're right when you say the only way to find out is to wait and see. im confident I'll never
want to be part of the cohort of doctors who see their job as monotonous
