Alright, let's put it this way:

Saying that you don't have much of a right to call yourself a writer if you never finish anything ever is not presuming to be "the emminece on who is or isn't a writer," or some sort of Writer God. That's because finishing something, sometimes is such a pathetically low place to set the bar. How the fuck do you call yourself a writer if you never finish your work? Answer me that.

Also, there's no such word as "emminece." Were you trying to say "eminence"? How cute.
