Take a look at 5 TV Rules That Aren’t Rules Anymore. Some of the best writing in any medium is on long-form television right now (and yes, I know some of them are adapted from books). Point being, challenge your assumptions. Take risks. Think about what scares you the most and go do it (keep it legal and moral, please). That character, scene, bit, or riff that you love? Twist it. Destroy it and see what happens. Maybe you’ll restore it. Or maybe you’ll find greatness. Have fun.
What if you write a scene of sex, violence, or intense emotion and focus only on one of the character’s body parts? Oh stop, not the obvious ones either. And yeah, I’m being silly with the crab legs. Have some fun, for goodness sake.
What would happen if you select just one of the senses and focused an entire scene through it?
As far as sensory detail goes, the sense of smell is often overlooked. Writing can gain power not only with focus, but with the specific. Simple words can pack the most punch. Try zeroing in on only what your character smells in a paragraph and see where it takes you. It needn’t be as dark as Apocalypse Now, but it can be just as memorable.
Aaron Gansky discusses deeply imagining over at his blog. Check it out, then spend some time daydreaming (purposeful daydreaming, that is). Then of course, you have to write it down.
