Too Critical not at all critical

So what does it mean to be able to write anyway? I mean what defines a good writer or even a brilliant writer. I think it is important for one to get their thoughts down onto paper. Which for some may sound easy but I assure you it is easier said then done. Too critical not at all critical. In this I'm trying to express my view on writers always reviewing their work repeatedly to the point where is it so far removed from their initial thought it doesn’t even correspond. Editing, not at all critical.
