Always traveling these days! This time with no internet. Just got back from a trip up north to a cabin with my writing partner RoseAnna. We've been doing this since we were kids. I strongly belief in writing partners, and not just for fiction. Although RoseAnna writes fiction, she spent most of the week working on her dissertation. I also strongly believe in writing retreats. Sure, we took a hike every day, though most of what we talked about was our writing even then, and we went to the Amish bakery. But really, we got up every day, got our breakfasts and caffeine, and worked. We worked until six or so. Hiked, and then had dinner. Then sometimes went back to work, and then sometimes knocking off for the night.
Writing retreats are great because you are out of your normal. Sure, a cabin still has dishes you might wash, and a toilet you have to flush with a bucket of creek water. But I feel less likely to decide I have to scrub the bathroom with a toothbrush in order to avoid my writing. On top of that, my writing feels shiny and new just because I'm not stuck in my own house. You go for long walks and think. Your responsibilities are down to the basics.
Writing partners are great, too. For one, someone else is sitting in the room working, and you feel like a jerk not working, too. For another, when you get stuck, you can interrupt the other person and ask that when they get to a good stopping point you can talk. Then you can talk about what you are stuck on--get fresh eyes immediately and help each other out.
Writing is never as mystic as readers may think it may be, or writers may want it to be. We have a series of skills and tools to get there just like every other job.
