The ritual used to be write 5 days, read 2 days. Write 5, read 2. Never read the genre or sub-genre in which I was writing. Different genres--even non-fiction--were necessary to unclog creative paths and to allow my mind to explore strange rabbit holes.
Lately, I write every day, working on the same story. No breaks until the WiP is done. Trust me, that's not only a bad idea; it's worse in implementation. Especially since I write so slowly. It leads to work-avoidance, burnout, and obsessing over the wrong things.
The other reason I broke the habit? I'm not proud to say it's gotten harder and harder for me to park my "editor" mode when I pick up someone else's work. I've spent a lot of money on books that I cannot finish. I get angry at the author for not trying harder. I'm furious at the editor for not insisting on certain fixes. It's all the criticism I heap on myself being redirected at someone else's finished product. I got issues. I know.
Maybe I'll try to get back on the reading-regularly bandwagon in 2017. I miss it. Like that dear friend I keep meaning to call yet never do.
