“Every block of stone has a statue inside it and it is the task of the sculptor to discover it.” - Michelangelo

I take the approach that the first draft is the rough stone of which the story will, eventually, be hewn. If the first draft is rough, that's perfectly fine, and if it isn't awesome, that's something i can fix in the editing phase. So long as the fundamentals are good and the premise is workable, it's worth pursuing.
