Homework is about two main things: learning, and preparation. You've got to learn new concepts, but you've also got to prepare yourself to be doing the real work in the future, whether it's taking the math test or writing the story. Homework is like the stretching before the big run: it's essential warm-up to make your run the best it can be. And just like the marathon or the math test, creative writing benefits from a little stretching beforehand.
1. Do Your Research.This is the most obvious form that homework takes when you're doing creative writing. Some stories require specialized information, and even not highly technical stories usually benefit from more detail. If you're writing a story that is set on a farm, for example, it's important that you know when planting season is and how the procedure of milking a cow happens. So before you start your next story, take a few notes on the setting, the street names, the procedures and shop talk of the world you intend to inhabit.
