I've discovered the value of adding "writing" to a large chunk of my smartphone's calendar, every single day. No meetings, no coffee dates, just "writing."
Writing, of course, means powering through a solid hour of wordsmithing and critical thinking, then taking a break, usually involving wood chopping, dog-running, or baking. Baking is an excellent respite from writing, I have found. Or, at least, a peace offering to the family for which I have forgotten to provide clean laundry. At any rate, the hour on-hour off system seems comfortable enough.
The edit process is a fascinatinating journey through my own psyche. Am I really up to this? What if I change things around and it's not the same book, anymore? Oh no, that great idea I had at 4 a.m. - I can't remember what it was!
I'm aware of every word I add or delete, every descriptive sentence I carefully script, where it goes. I know about every restaurant, every hotel, every attraction, and I can't help but think I owe future readers more than just a listing of places to go and things to do.
A careful, thoughtful, process.
