I do. Every time I write something and have someone critique it they come up with a better sentence, and when I take the better sentence and modify it and have someone else critique it, they once again come up with a better sentence than the one I just modified. What's the point in writing if someone is just going to write it better? (Don't worry I'm still writing, I'm just kind of ranting because it seems like no matter how much I write it's still not good enough even with revisions). I guess I got to learn to be content.
