Like for the people who jizz at calculing derivatives and integrals.
What is so fun about it?
I mean, I am not good drawing, but I do understand the fun with the pencil, making doodles of sexy anime girls and enjoying creating something (even if these drawings are shit and cringeworthy).

But I don't see the enjoyment in doing numbers, like, you must be mentally impaired to find numbers arousing.
Like who in his sanity cooms to numbers?
What's the enjoyment in that?

I can picture someone with certainty, to draw for hours, but I can't picture anyone in his sanity to spend his day solving calculus in his room while he could be better off playing vidya.

Can someone explain this to me?
It's a legit question.
