I'm curious: what field did you work in? One of my reasons for not pursuing math was going to a summer undergrad research mentoring thing by a well-known-enough American algebraic topologist (the field that Eugenia works in), and finding out that even his students were having problem getting positions in higher ed in the US that weren't temporary – that was simply the state in general academia, with an ageing professoriate. Maybe I should add a 5th point, but I need to phrase it very cautiously. 5. If you're interested in doing mathematics in an institution of higher ed in the US, focus your work on teaching, and be prepared to live in the middle of nowhere.
