[Espy]

I do a lot of art (sketches, doodling, mostly), so most of my writing posture derives from my art posture. I generally use my wrist, elbow, and shoulder equally, but if I'm trying to write quickly and I'm stressed (eg exams), my shoulder tends to lock up, and then my wrist gets overworked and starts hurting afterwards.

Also happens if I'm doing a pencil drawing and I'm trying to not smudge shit.
