Perfectionism is when you simply do not want to stop writing or editing. It never will be perfect, but you keep wanting to try and try. You have to just stop yourself at a point and say this is all I can do. It is finished and send it out there. It is difficult because, yes, there could be a typo hidden in there, And I know I loath that. But we have to stop at some point and accept we have done the most we can, because if you edit too much , you will change too much, want to keep on changing and editing… until it is nothing like the original.
