I'm fucking bad at Math, I don't understand it. I generally pull low Bs in math at most. I'm good at discrete math though.
I also have absolutely NO interest in common lab sciences (physics, chemistry, bio, etc).
I think if I put my mind to it I could be a good scientist, but I just don't care enough to put forth the effort. Science requires too much formal planning, data recording, self-checking, proofing, etc. I HATE that stuff. If I want to do something, I will do it my own way and don't want to have to worry about standards, safe guards, writing up formal reports, etc.
I'm VERY into philosophy and computer programming / hardware though, as well as creative writing and anything that requires a good imagination.
