This in-between moment is a great time to do some free writing...and I mean really free writing. Here's the technique I use to break free of any boundaries and get my creative sap flowing:
1. Set aside at least fifteen minutes of free time. You'll need at least this much to get past the initial awkward fumbling and start to produce quality stuff.
2. Use old fashioned pen and paper. One of those journals you always get as birthday gifts could work too. Do NOT attempt this on the computer. Won't work.
3. Start writing. About anything: what you see, what you're thinking about, what you did yesterday. The content doesn't matter. What matters is to keep writing. Keep the pen moving on the paper for the entire fifteen minutes. If you can't think of anything to write about, write your name over and over, or "I don't know what to write," or, heck, maybe a curse word or two. Just KEEP WRITING.
This technique is sort of a colon cleanse for your creativity (pardon the metaphor). It gets all the junk out at the front of your mind, making room for the really good stuff. By keeping your hand moving, you are also instantly ready to write down what ever pops into your head...no pauses, no picking the pen back up, no spellcheck or green grammar error lines. What you'll be left with, especially if you practice this technique, is an abundance of fresh, original writing, as new as the thousands of leaves soon to unfold.
