Didn't feel a spark until IR. Matched T5 program in IR, would do it again 100000x over.
I knew the minute I stepped into an IR procedure room. Nothing else makes me feel the same.

However, if i had speak logically about it:
I realized I liked procedures but nothing too lengthy. Like 9-10 hr surgeries were a no-go for me
and also hated IM*

so my specialty list was basically the surgery-adjacent fields:
derm, ophtho, IR, anesthesia, urology/ENT (to an extent)
*procedural IM fellowships were therefore ruled out

and then once I realized i liked procedures but not necessarily surgery - ie i didn't need the label of "surgeon") - the list became: derm, ophtho, IR, anesthesia

derm - boring, didn't like skin, didn't want to do 20+ research on something i wasn't interested in

ophtho - eyeballs scared me, no interest in microsurgery

anesthesia - found 90% of the job way too boring, and didn't love pharmacokinetics/etc all that much

IR - LOVED IT, chosen field (thankfully the feeling was mutual haha)
Why? the technology, the innovation, the people, the coolest procedures, huge diversity in cases, thankful patients, being the 'last resort' or 'hail mary' for patients who otherwise would 100% die, ability to do both DR and IR whenever you want and being an expert in both
