Lots of NaNoWriMo participants give up reading during the challenge. Sometimes it’s because of lack of time but for many it’s because they don’t want to get sidetracked with an another author’s work.
My tip of the day is keep reading during November. I’ve had days where the muse seems on vacation, but oftentimes taking a break to read, even if it’s just for fifteen minutes, is all that’s needed to kick-start it. There’s something about reading what’s in another author’s head that sparks your own creativity.
