That is, how much does anyone care about the name brand of your degree, in the "real" world? I think that the stress from grades, gpa, etc. is causing me to lose focus of the reason I like mathematics in the first place, and the reason I'm working so hard on just getting points is because of graduate school. But does graduate school really matter? Or does the "real" world care less about the shiny degree and more about the actual research you do? Is it really worth it constantly stressing over the name recognition of potential graduate schools? Especially since my realistic chances of making it into a "top" program are slim?
