Is it normal to want to keep going back and rewriting everything? I don't mean rewriting as in restructuring things or choosing better words or imagery or anything of the sort. But going back and rewriting from the beginning completely without even looking at your previous writing. I don't want to move forwards sometimes, just back to the beginning and doing it all over (though the later parts and even ending has already been written in my head, in actual words).
I am very new to writing, but I think the general advice is to keep going until the end so you have a first draft. And then start editing. How do you all do it?
