Edit: This question is now closed for being not related to math, but many people pointed out that becoming an actuary is one of the most viable career path for someone with skills in pure math.
Noone I've ever talked to knows what mathematicians do when they drop out of grad school or fail a postdoc or don't get tenure. That's because professors are exactly the people that didn't experience those things, and don't seem to keep in contact with those that do.
I went to an AMS research session for recent grads over the summer, and they admitted that they don't know either, and that they are planning to do a study or two to find out.
My question is this: for those who planned on a career in pure math and then stopped at some point by choice or otherwise, what do you do now?
I'd also be interested in anecdotes about friends and other students you know or knew, and also other related stories.
As for my stories, I have a friend with a PhD in pure math who teaches at a cool private high school, but everyone else I know is at a teaching college or a postdoc or still in school.
