In the long run, the quality of your work is all that matters. That is your only resumรฉ. Be professional. Make sure your editor or publisher can always reach you. Do what's asked of you if your conscience can bear it. But know that, five years from now, as fans or prospective employers are looking over your published pages, no one will care that this story sucks because the publisher moved the deadline up or because the editor made you work an android cow into the story. All they will care about is what they see in front of them, and they will hold you responsible for it, no one else.
Mark WaidThe most basic definition of a story is 'Somebody wants something and something's in his way,' and I'm more likely to be engaged if I at least think I know what those two 'somethings' are. They can be simple, they can be complex, but - particularly if you're a beginning writer - I'd rather you err on the side of revealing too much than too little.
Mark WaidEach time I think I've made a connection with someone... once they find out what I can do, whether it's hours or days later, everything changes. Invariably they freak. They get retroactively paranoid, wondering what else Clark Kent is hiding from them.
