I don't know how others write.
For me, I have certain scenes in mind and then write the lead-in. Then the fall-out. Once I have the event fleshed out, I figure out how to bridge from the previous cluster to the one I just wrote.
Mrs ERJ recently advised that I allow the segments to run a little longer when events are moving faster. Character development is all well and good but a thousand words is more than enough.
"Don't leave the readers hanging when the lead is flying." was her advice.
That means some future segments might get a wee bit longish. There was just not a handy place to snip them.
I reserve the right to have an air bubble. So far the words have come easily. Sometimes too easily. It gets awkward when I have three weeks of story queued up. I have been letting is spin down and one or two new characters will be worming their way into the story soon.
Some of the segments wander into areas where I am a rookie. Please, bust my chops. That is the only way I will get better.
Thanks for reading.
