Common advice for writers is to put the seat of their pants on the seat of a chair and turn on their computer and start writing. This advice always gets a good laugh because everyone knows writing good fiction is a lot more complex than that.
But it’s good advice nevertheless. Some day when the muses are avoiding you like the plague, try it. Doesn’t matter if you have an idea or not. Just sit there and start writing. The alphabet. Drivel. Anything.
Because the physical act of writing causes something to happen. It’s like those laugh therapy groups. Even if you aren’t in a laughing mood, the physical act of laughing changes your body’s chemistry for the better and, before you know it, good things are happening to your body.
Same principle applies because the physical act of putting words on paper changes your mind’s chemistry and slants it towards writing something viable. What mind wants to scribble dribble forever? Even on the worst days, my mind … and yours … wants to do something worthwhile. So the rest is just a matter of figuring out where your mind wants to go and going there.
Okay, the first few lines … or paragraphs … or pages … might end up in the waste basket as you and your mind come to agreement as to where you are heading. But the rest could be pure gold.
