I can and I have. It's easy and trivial.
Then that is awesome. You have my congrats.
Now, of course, you wouldn't expect your rough drafts to be published. That's what editors are for.
Of course not. That's also what polishing a manuscript until it's reflective before it ever gets to an editor is for.
It's also easy to bluntly label anything you haven't read as "slushpiles" or whatever. I read anything and everything that I can find. That's what good writers are willing to do. All in all, it's not so much your ability to output words that's in question so much as your ability to input things other people have suggested into your imagination.
When I mentioned slushpiles, I was talking about actual slushpiles - things submitted for publication in some form (in my case, it was for Elfwood and Woodworks some years ago). I have not the time, inclination, or patience to do it again; working as editor for one friend's comic and doing serious beta reading for another is as far as I'm willing to go any more. I have my own things to write and books to read, and I do not think I am missing out. Fanfic is included in this, but for different reasons; I am generally not interested in what other people think should have happened in someone else's imaginary world. Compound this with my partial hermitage from popular culture (don't watch tv, watch very few movies, low interest in anime and most comics), and one could say I have an interest level that is a number approaching zero.
I read the back of cereal boxes when I eat breakfast in the morning and have since I started reading. So what? After a point - working full time and supporting myself was what did it for me, although now it's maintaining 6 hours of class a day, a marriage, and a household - I've lacked the time to read
everything for the sake of reading it. I
have to be choosy, I no longer have the free time to read a book a day. I spent plenty of time slogging my way through crap I wanted to throw against the wall as a kid to get a good idea of what doesn't work and I'd rather read things I enjoy now that my time is far more limited.
I find it doubly important that I be choosy now that I am trying to write seriously - one is what one reads, and I find that when I read silly, fluffy, stupid stories, my writing comes quickly... and is silly, lightweight, and stupid. On that note, I have to limit how many classics I read in a month or I start writing prose that is painfully purple. Dickens is the worst for this - you might think that I am wordy
now...It's like chocolate. It's important to sample a variety to know what is good (or simply to one's taste) and what is bad (or not to one's taste), but life is too short to waste on indiscriminately eating the bad stuff, no matter how cheap it is.
