I have the same with code. I only read or write simple stuff. I used to like mathematics on school, until I just couldn't follow it anymore. It got me hot (physically), with headache akin to migraine. Which gotten worse throughout the years I studied. Now I tend to avoid such state. Its not worth the hassle.

There's a couple of professions/qualities I have a lot of respect for, mathematicians is one of them. I appreciate them for three reasons: their ability to deal with the sheer complexity correctly and calmly, the fact it is unbiased, like science used to be (or rather: a couple of sciences aren't). The third reason is the one outlined above, generally: its a quality I've been unable to possess.
