I know what you mean. Lately, I am averaging a page a day.
All because I stopped writing mine at some point. I needed to rewrite it, because the way i had done it bugged me too much.
I had told myself I would edit the first part ( which I had finished a while back), but stupid me, I continued the editing into the second part.
Sure i loved all the changes i have done, but since then I have problems writing because, of course, it does not come out as good as the parts I have corrected.
As for writing without editing... that is what they say on that website. Even if it makes you cringe, do not touch it back.
Yeah... easier said than done.
Maybe next one
If there is one.....
