Since "Ray Bradbury" is the only hint as to what this could be (unless you're familiar with the mentioned challenge), and since I often look to comments to get a feel for the link's subject before even following it, I'll just say what a great idea this is: that you become a "collector of metaphors" (love this) by reading one short story, one poem and one essay every night before sleep, which is a great time to do it because your brain can then best absorb the new info while you sleep. Arguably though, I'd place the time before the first sleep and the second sleep as even better (for those not aware, called segmented sleep and supposedly a natural thing for humans before electricity), since you have a couple hours still to comtemplate and/or get inspired by the material while in a quasi-meditative state. I got to sleep this way during a few weeks and I've easily written my best fiction passages in these hours, they came so naturally and effortlessly, like my mind and focus were sharp as a razor whereas normally I'm all around the place (as you can see in this comment.)
