I've always been obsessed with my handwriting and trying to make it perfect.
My handwriting looks like this while taking notes in class, but sometimes I will leave spaces and draw the diagrams in later, like with the electromagnetic spectrum rainbows up there. I usually have a few different colored pens on me, and I always carry a ruler.
Also, I spent a few years at a fine art school in San Francisco, so people shouldn't compare themselves to me much. I wonder how many other people have hated their art so much they went back to school to study math instead

This is the most embarrassing piece of work since Clint Eastwood painted his wagon.
