Cross-training is a concept I snagged from athletics. It's a way of improving fitness for one particular sport (or art) by practicing another. The idea is that the body adapts to repetitive exercises and, by becoming more efficient, shows slower progress.
Over the years, I've noticed that if I'm stuck on a story and can't figure out how to even think my way toward a solution, one of the most helpful things I can do is to listen to other storytellers talk about their work. In particular, I'd put on one of those bonus material discs from a favorite movie and listen to directors and screenplay writers discuss their approaches. (My favorites are Peter Jackson, Fran Walsh, and Philippa Boyens talking about how they adapted The Lord of the Rings into film, how they decided what to leave out, what to expand or re-arrange, that sort of thing; because I know the books so well, I can follow their interpretive process.) I come away re-charged because the story-telling is similar enough and yet different enough from what I do in prose. I've also gotten much good perspective from books on screenplay writing for much the same reason. I don't want to write a script for a movie or a play, but I do benefit from that particular way of looking at story, character, dialog, and action.
