One way to put aside that nagging internal editor who has you going over your work multiple times and keeping you for making forward progress is to engage in a "fast" writing endeavor. Many people join Na-No, which I've never tried. However, my local RWA writing group sets aside one week each month for a "Power Draft". We start on Saturday and end on Saturday.
We have established a yahoo group and each of us post what our goal for the week will be. We are each accountable for posting our progress at the end of each day. The loop allows us to encourage each other, post stumbling blocks, etc.
Making yourself accountable for reaching a goal can help silence that editor. But, you must allow yourself the privilege of writing without going back and reading or editing. Just continue writing towards each goal. It's important to discipline yourself not to go back and read what you've written.
Once you have gotten into the pattern of reaching goals on a daily basis, you'll be amazed at how fast the pages rack up. When you reach the end of that first draft, pat yourself on the back! That's a major milestone. At that time, you can bring your internal editor out and allow her to read your draft. There will be things to change, but that is why we do edits! Allow for at least three different edits...but more for that at a later date.
For now, establish a goal. Put it in writing. Make yourself accountable, and write that first draft!
Thanks for stopping by.
