I've seen similar questions on here before so I'm sorry if it's a duplicate or anything.
Frequently, I find myself in despair at my postdoc prospects as a result of the reputation of the university at which I am doing a PhD. It's ranked around 30-40th in the UK and, in some places, worse than 350th in the world.
I study Mathematics. In particular, I study a less popular version of group theory than average. So postdoctoral research fellowships are hard to come by as it is.
I could have gone to The University of St. Andrews for my PhD and in an area I prefer over my current one, had I not had a panic attack during my last exam in 2015. I kick myself over it most of the time. I still got the First required, only it was awarded the year later and the position had to start in 2015.
Compared to St. Andrews, my current university looks lame.
Sometimes, although mostly for my mental health, I have considered dropping out then applying to some other university, perhaps St. Andrews again, I don't know.
What's my question?
Well, this is not so much a question so far as it is a lament, I admit.
What I want to ask is this:
What do I do to become a marketable mathematician? How do I get a postdoc?
Also . . .
How do I let go of the "once in a lifetime" PhD position I could have had?
Any advice would be appreciated.
