I hate math because it did not come easily to me.
Because I have a lack of patience, I tend to give up the ghost on things I don't automatically do well and enjoy. Like, it's a waste of effort and energy to invest in things I don't do well - to express this in math, let me say:
If I have a cost of 1 and a benefit of 10, I think this is cool shit. But if I have a cost of 10 and a benefit of 1, that blows. And well, math was always a 10:1 cost:benefit ratio.
