I budget time for writing, but I don't write every day (I personally don't think you should). I think of it more like averages. If over the course of a week, I get say, 7,000 words in, that's essentially the equivalent of 1,000 words a day, even if I only wrote two or three of the days. Setting rigorous schedules on a daily basis is a bit too committed even for me, so I set weekly if not monthly timelines to make sure I don't get sick of the craft.
If I'm committed on a longer term project that I know I want to finish, I typically drop all my reading responsibilities and write until completion. I keep to one, maybe two things at a time, but I make sure I'm not working on the same length of work at the same time. For instance, if I have a novella, I try to have a short story on the side to supplement when I'm burned out. Maybe if I'm sick of one thing, I'll go back and do edit work on another. With novels or webnovels, it's a bit harder to say, I have very little experience in this regard, but my current methodology based on the one or two novels that I did end up completing was essentially one to two month spurts to completion followed by several weeks of editing, followed by maybe one or two months of rest away from writing.
And when I'm not writing, I'm reading!
