I have found that when I record the number of words I’ve written every day, I hold myself MUCH MORE accountable… er… to me. It’s rather like eating or exercising. When you write down everything you shoot past your lips, you get a fairly accurate reading on how many calories you have eaten. When you put on the timer and exercise, v.s. “oh, that’s good enough; I’ve got other things to do now,” then you know exactly how much you’ve exercised.
Do the same with writing. Record your daily word count. I used to record emails and journaling, and would have counted my blogs, too, but I don’t do that any more. It feels like I’m cheating. My DWC (daily word count) is for actual someday-this-puppy’s-gonna-get-published writing, even if it’s background stuff, or very drecky rough draft stuff.
So, write, and record. Hold yourself accountable.
