Here's another simple step to improve as a writer--to sparklefy your writing ...
Block your bickering brains.
When you write, you have two "brains" available: your creative brain and your technical brain.
All your creative brain wants to do is come up with good stuff to say. And all your technical brain wants to do is tell your creative brain how to say it.
Your creative brain might come up with something like this:
"She sits the on kouch. She is snozing. She is 54 years old."
Your creative brain may have given you the makings of a great story here.
But your technical brain says, "Wait a minute. I can see several ways you can tell this story in a much more engaging way. First, since I'm your other brain, I know you're talking about your cat. You will want to communicate that in some way to your reader. Second, you misspelled two words that will distract the reader from the story. Third, you need to swap the words "the" and "on." Fourth, you should vary your sentence structure so your story will flow better. And fifth, you should check your facts; cats don't live until age 54."
Both brains are important!
You could listen to both brains while you write, coming up with the building blocks of the story and arranging them as you go. I used to write this way, and what I found was that I listened to my technical brain so much that I lost track of what I wanted to say! I also slowed way down, sometimes not even finishing, because I got so bogged down with the technical aspects.
As an editor, I use my technical brain almost constantly, letting my creative brain snooze on the couch most of the day. But as I have been writing my own book of late, I find using one brain at a time to be much more effective. I write the first draft quickly, not worrying about spelling, syntax (word arrangement), and verifying facts. I just write, write, write, getting all that creative wonder down. Then I do all the technical stuff on the second draft.
Block your brains from bickering, actually finish your manuscript, and enjoy the writing process more by listening to one brain at a time!
