"I have to focus on what exactly I want to change, and how I want it to change. Like... I don't need to specifically know the anatomical details or anything, but I need to kinda will my bones to do this and move there and look like that, and my eyes to turn this particular colour, stuff like that. And sometimes the stuff I have to change is all related in different ways, and so I have to focus on it all at the same time, or do it just a little bit here and a little bit there, and sometimes if I do it too much the wrong way it can get in painful positions until I fix it."
