My plan was to get a MSc in Math, but I figured that no one (= employers) would care in the end, given my career in software development already. When I realized even I didn't care about the degree, I just stopped. But I do think the material is interesting. So I want to learn in my spare time. I think that's the best alternative for me, as I don't dream about working in academia etc. I was never a stellar student (in a university setting) anyway. I want to build a stronger foundation in statistics and probability theory. The goal I have in mind is to try and dabble with systematic trading.
