I just graduated from University, and I intuitively believed that taking more math would make me a smarter person. So although my major was Psych, I took courses in Analysis, Algebra, Discrete, and Number Theory. Of course, potential employers have neither seem to have given a fuck nor realized just how difficult Analysis was, but whatever-
I even implemented the thinking style I picked up in Analysis, such as the notion of a compact space [as it relates to social cohesion], while writing a paper on Aristotle's Politics in my sophomore year. I didn't use any math words at all, and instead drew a diagram to illustrate what I meant, and really enhanced my argument.
Anyway, bottom line: I took a shitload of math to make myself smarter and to enhance my nerd cred; nobody seems to care; maybe someone here will give a care; since I'm ultimately probably going to be self-employed anyway, perhaps my improved mental acumen will pay off financially, but as of yet it's unclear.
