In such a situation, ask yourself:
1. Is everything you downloaded carefully archived and cherished, or disposable?
2. How much of your bandwidth usage is "fire and forget" stuff like full series of anime/TV shows or complete games?
3. Do you download things for the hell of it? Like downloading a raw shortly before a sub is released, or downloading a random episode of something you don't watch to see a few minutes of oft-discussed footage (y halo thar Mizore).
