Will I hit an "intellectual wall" with math? Every so briefly, for one semester, I was a math major in college. I got lazy and wussed out and graduated with a liberal arts degree. 7 years later I'm feeling pretty dissatisfied with my career and long term job prospects. Seems like quantitative fields have better prospects. That combined with the feeling of personal challenge from a sense that I didn't adquately challenge myself back in college has me thinking of doing either a Masters in Statistics or a 2nd BS or MS in Comp Sci. And i'm starting basically from scratch, probably will take math courses at a community college first to do prereqs. That being said, the biggest fear I had back in college is something I still have. If you study something like math or comp sci, is there a point you hit an intellectual wall, where simply if you aren't smart enough, you just can't get the material and you won't pass the class? Or is hard work more of the determining factor? I was a fairly solid math student in HS and did ok in the intro calculus classes in college (Bs) but I was never the math whiz that was taking calculus in middle school or anything like that.
