The world looks different when you’re eighteen and when you’re thirty – in some cases because your perspective has evolved, other times because the world has changed. Men and women drawn to careers in medicine while in high school or college are finding that when they emerge on the other side, things aren’t quite what they expected.
Typically, this is portrayed as the (well-worn) “Narrative of Disillusionment” – i.e. idealistic youth drawn to help people discover the practice of medicine is more rushed/bureaucratic/corporate/burdensome than they were expecting, and now are searching for new opportunities. While there’s a measure of truth to this arc, I’m not sure how different it is from any other career choice, which tend to be attractive in the abstract (A prosecutor! A screenwriter! A journalist!), perhaps less so when you’re actually doing it.
