"focus" is an important term that I'd like to focus upon.
Almost everyone in this line of work started off in a different direction, sometime quite radically so. One guy we placed did serious work fighting global capitalism before joining a large bank
But he focused on his previous line of work well, and before that he had focused on a clear line of studies. Now he focuses on quantish work.
An "ideal" CV basically says:
Set out to do hard thing 1, when I finished that,
I did hard thing 2, when I finished that,
I did hard thing 3, when I finished that,
I did hard thing 4, when I finished that,
Rare of course, but you need to show that you can commit to things, as well as being smart enough to do them well.
You also need a thick skin to do this line of work, and in Francis posts I perceive that this needs to be worked on as a priority.
As it happens many people in quant finance are what most people think of as geniuses.
A PhD in a hard topic is not exactly rare, I have >1,000 PhD physicists on my database.
That of itself is not genius, but a few have written serious books appreciated by their peers.
Again that's not quite genius, but we have loads of people who've won national awards for cleverness, varying from impressive scholarships, winning the Chinese national physics olympiad, top first in maths from Oxford (for one year we have the 1st and second).
Also some have made big piles of money by being smart, which impresses me
Drifting aimlessly around midscale academia does not impress me.
Some people, like you perhaps think that my job as a headhunter is to be nice to people.
That's just naive.
I'm honest with people, I'm rich and good looking enough that loads of people are nice to me, and thus I don't value it as much as you do.
I do value honesty, and I see my role as an amplification term. If I think you can make it in this line of work, then I will illuminate ways forward. But a certain % of the people that reach me are simply not cut out for this line of work.
I see it as cruel to give them false hope, since most have the ability to succeed somewhere more suited to their talents.
I will never be a professional sportsman, this was never going to happen, I knew this by age 8. Thus I wasted no time on this when doing things with numbers, computers and dodgy chemicals all offered good careers.
You need to step back and find a role model. I don't mean an inspirational figure like me, but someone who you think is both like you ,and who you would like to be.
