As an academic, so a full-time writer, getting to the point of 'decent writing' took years and about 50% of my work-time so far. The key was never stopping writing (500 words per day on a weekly average) coupled with external, sometimes brutal editoring/reviewing (in this case, from my supervisors). I think external editing/reviewing is key. A sentence you've reworked ten times sounds perfectly reasonable to you because you've read it hundreds of times, but to someone else it may unintelligible garbage. I'm not sure how your different edited drafts differ. Are they details? For me I first sit down and think of the 'one' story I want my data to tell, from there flows only one single possible draft.
