Brandon Sanderson also has new favourite words/ expressions for each book. In one book, everyone did everything ‘for some reason’. It annoyed me so much. Especially since the reason was sometimes obvious (like someone being solemn for some reason after a character died.) I had a whole list of these words, a new bad habit for every new book, so to speak.
I have a hard time forming clear pictures in my mind. Funny enough, I’m not bad at drawing people, so, for some books I followed the description to draw the faces of some characters, sometimes really feeling I got it right. I also take pictures of landscapes that remind me of stories I like, so I can look at them again because I won’t be able to recall them exactly.
