I noticed I was getting slowly burnt out on reading theory. Haven't been as consistent in the past few weeks as I would like.
I'll take a short break from it and read some fiction, mainly to keep the habit up. I find I'm less likely to want to read if it always feels like studying.
I know some people tend to read multiple books concurrently, but I never tried it. How does that work out?
When I start reading a book, I just read it to completion before starting another one, regardless of fiction or non-fiction.
