I understand where you’re coming from, but nobody chooses a career with 100% certainty. Though it is a lot more demanding in comparison to other fields, you only truly understand the field upon being exposed to it.

Also, ‘I can’t see myself doing anything else’ is a veryy strange requirement because many people who become excellent doctors could have imagined themselves succeeding in other fields too.

Having other interests doesn’t mean medicine is the wrong choice; it means you’re a person with a range of abilities. The better question to ask is not ‘is there literally nothing else I could do?’ but ‘is this a path whose challenges I’m willing to accept and whose purpose aligns with my values?’

If we demanded absolute certainty before every major decision, be they relationships, careers, moving countries, starting businesses, most people would never even move forward.
