Every so often, about once or twice a month, I drag my laptop to the nearest Starbucks without internet. I settle in with a venti coffee, plug in my earbuds, and start to write. I usually manage to get a lot of work done, or at least make some decent headway.
Yesterday, I managed to work through a pacing problem in the first draft that had been annoying me since last October. I nearly pumped my arm in the air, drunk on that 'this is going to be so much better than my first draft' feeling.
So, yes, yesterday was definitely a good writing day. *g*
