There's homework with this one. Sol Stein says to include "a little unobtrusive poetry". Natalie Goldberg says "detail is the only poetry you need". Children are amazing at observing the little details and it's what brings life to your writing. Spend 10 - 20 minutes per day writing what I call a "close observation exercise". To do this, you can think of some memory or some moment in your day. Freeze frame. Now describe it: sights, smells, the quality of light. Name things specifically: Instead of "We talked about _____ over lunch", "We talked about _____ over cafeteria burritos." See the difference? Set aside 10 minutes/day and you'll awaken your senses. What's more, it will overflow to your fiction. Let's share our favorites or just talk about the experience if you are uncomfortable reading your work aloud. Rule #1: no editing. Just keep your pen moving. You'll break through to "first thoughts", i.e. the good stuff in your subconscious.
I have more success when I schedule it. A lunch break is long enough, or waiting at the doctor's office, over morning coffee.
