I've been stuck before - musing over some scene, trying to capture some narrative nuance or perfect a bit of dialogue while all around me time slows down. It certainly slows down when it come to productivity as I stare at the screen, check Facebook, glance at a sales report, and then come back to the half written paragraph.
You see I'm a bit spoiled - I've been writing two first person memoirs this year as part of my Scarlet Bastards series, so I've been in a certain mode when it comes to pumping out prose. With my latest, The Scarlet Bastards - The Bone Witch, waiting for its next step in the editing process and the next one still cooling on the back burner, I've moved back to the third of my military scifi books, Titan Rising. Third person narrative much heavier on tech, math, and science than the other series, and here the narrative has ground to a halt.
I'm fortunate that the weather is good, the gardens needs tending, and the chickens need looking after. It gives me something to do while I figure out what word comes next in that unfinished paragraph.
