I am a little late to reply, but I wanted to anyway from my experience as a Harvard physics PhD that is choosing to leave academia:

Many PhD programs are their own bubble, and many students don't seriously consider outside opportunities because of it. I honestly do not believe many of the students would be there if they had more exposure to basically anything outside of research, and more students would also consider other opportunities earlier if there was more exposure or a better connection. I really wish internships were better embraced by physics PhD's, but the current competitive culture combined with disagreeable professors makes it not encouraged. (Not to mention the fact that a 3 month internship is a drop in a bucket for a 6+ year PhD)

Otherwise, it is great to hear this person decided to leave their PhD program and found happiness (regardless of what she is doing). One thing I tell people who aren't sure about what they want to do post-graduation (e.g. most physics PhD's), or even if they aren't a good fit for the group they are in: if you took an entire month off from your PhD to make that decision would you regret it? I personally believe in almost all cases you wouldn't.

Strangely, many students seem to either default to a postdoc or put a half-assed effort towards finding an industry job.
