Programming can be like that. You write some code, but it doesn’t work! Just one small mistake. You go look for it, try to fix it. Just one more try. Solved! Endorphin rush. And you write the next bit of code. And then the sun comes up.
How do you create an addiction like that for drawing?
Try to find a nice looking subject that is *just* out of reach, and then keep at it until you get it right, and then feel that rush of endorphins!
