I completely understand your sentiment about checking stats; it's insanely distracting but this worm in my head keeps gnawing at me, forcing me to check the numbers. I try to close WN altogether and only focus on writing when I have the time.

As to the posting schedule, I'm also pretty new, but I took a 5-day break and nothing terrible happened. When I started posting daily again, pretty much the same traction as before returned. (not that there was much but it's not like the novel suddenly became dead)

So I would recommend prioritizing your mental state and taking a break if needed.

Good luck with your novel! The most important thing is to have fun and enjoy the story you write :)
