If you want good advice, don't ever listen to a teacher.
Those that Can Do, Do ! Those that can't Do, eventually end up trying to teach.
As far as Astrophysics, Applied Math, MetaPhysics & albeit Philosophy in a way goes, all I know is your chosen field beats the hell out of the Cosmology hands down......there is Speculation, Pure Speculation, then there is Cosmology......Go with your dream. Do what you need to do to make it happen.
Even if you don't make it, I'll look forward to having a good conversation with the next guy that serves me a Big Mac
