I hadn't thought of using binaural beats! I use those for sleep.

I've done several sprints already, but I have definitely hit a spot that leaves me somewhat stalled. It feels like every single word is forced and I don't know what should happen. I also feel like my story is wrapping up too quickly for my goal of at least 80k and that frustrates me, but I also don't want to JUST write words as filler, either.

Good for you for pushing past that 'roadblock' and going for it!
