When I was in middle school, more than a few times, I was called Suzie Homemaker. No, it didn't offend me, but it's definitely a bit of a preface for what comes next.
I cleaned today. You see, I do this, every now and again. When i can't come up with anything to write, or I just can't get up the gumption to work on my latest project, I clean. I clean like crazy. Today, it was my bedroom. I (finally) removed the rolls of Christmas wrapping paper, put the sheet and comforter back where they go, straightened out the curtain, boxed up all the excess.
And, as always, it helped. Too many things needing to be done make it impossible for me to get anything done. So I cleaned. I created a blank slate, both in my mind and in my surrounding space. I was able to find peace and zen and all that stuff. Okay, maybe not complete zen, but a good enough imitation that I can actually stomach the thought of leaving the real world for the story world again.
So, troubles with that creativity? Grab a rag and get your Cinderella on. I bet you $0.67 it helps.
