It's not about perfection
"I write slowly because I write badly. I have to rewrite everything many, many times just to achieve mediocrity. Time can give you a good critical perspective, and I often have to go slow so that I can look back on what sort of botch of things I made three months ago. Much of the stuff which I will finally publish, with all its flaws, as if it had been dashed off with a felt pen, will have begun eight or more years earlier, and worried and slowly chewed on and left for dead many times in the interim."
― William Gass
