Personally, I specialized in cryptography, did a few years of research in security, and now work in security. Note that I always liked programming (in fact I kind of chose math over eng pretty much randomly). To your point, I don't do a lot of math on a daily basis -- I see it more like painting/singing, you keep it as a passion, you don't do just that for living.
