I'm looking for a book with a spellcasting girl who sets goals for herself, and when she can't do it, she increases her goal for the next day.
The goals were like, "Cast this spell 100 times" and if she failed, "Cast this spell 200 times, with my left hand" or something.
I think she was one of two apprentices to a magic teacher, and the other student just did her spells well enough to just be able to cast it.
I want to say it was a book by Tamora Pierce, but I don't remember any character that acts like that in her books.
Or at least I think it was a book... I have the idea of images in my head, but that might just be remembering my own visualizations...
It's English, and wasn't recently published. I think I read it in Canada in 2010?
It might be a fanfic, in which case I'd likely never find it again? But I do think it's a physical book...
What else have I read
